Comments about Acoustic Lead Guitar Series G100FX 100W 1x12 Guitar Combo Amp:

I'm just an old picker that only plays Gospel now after many years of the club scene !!! I have a decent selection of BIG amps, Vintage DSL 50 through 2 4x12 cabs, Fender Twin Reverb, Johnson Millenium stereo 250, Fishman Loudbox Performer, Acoustic B200H through a couple of Cerwin Vega 18's. But I needed something smaller and lighter to take to church without using a dolly and several trips. I just needed something in the 40 to 65 watt range and I wanted at least a 10" speaker but I really prefer a 12" for a fuller sound. I'm going to mic it at church anyway but I also need to use it for my monitor since my church doesn't have enough monitor lines for me to listen back without mixing my guitar with another guitar and there are always balance issues. I studied about the Fender Mustangs and had decided that's what would work good for me after reading all the propaganda about them. I've been doing this long enough to know not to order one unheard though so yesterday I made the 100 mile drive to my nearest GC in Lewisville, TX. It took a couple of hours waiting my turn to try out the Mustang II and III. These are modeling amps and I'm sure they are good units when used for their intended purpose but they are pretty complex for an old bird and I just couldn't get the crystal clean tone I was looking for from either one of them. I decided that I just wasn't computer savvy enough to use one of these to their potential. Being very happy with my Acoustic bass rig I decided to try one of the Acoustic Lead series. Man am I glad I took that drive. I first tried the smaller one, 30 or 40 watts I'm not sure, and it sounded pretty good. I then tried the 100 watt version with 12" speaker and was very surprised. It doesn't have all the amp modeling features that the Fenders have but what it DOES have is a crystal clear rythm channel. It also has plenty of grit on the lead channel and PLENTY of volume on either channel. Not a lot of effects but it does have the necessary reverb/delay and also a nice chorus feature. Just the basic knobs and controls so I can easily get the sound I want. Even though it is rated at 100 watts when using an external speaker it's still pretty compact and weighs just over 30 lbs so I can carry it and my guitar at the same time. As I said earlier it is pretty basic as far as current amps go but it will do everything I need for church and not break the bank or my back. I don't have to wag around all the effect boxes either. Most of my old amps are tube and I really like them but they have came a very long way with solid state in the past 40 years. I don't need to peel the paint off the walls anymore but this little dude is way more than loud enough. Even at very high levels on the clean settings it is virtually distortion free. I plugged a 2x12 Marshall cab in the external jack and all it did was get BETTER !!!! Not ragging Fender as I am still a Fender fan, for what I needed this dude is awesome. Compact, lightweight, user friendly, killer tones and plenty of horsepower any small to medium venue and at 250 bucks I couldn't be happier. WHAT A DEAL !!!! And no, this is NOT a paid endorsement.

Awesome Sounds!!!

By Paul Hess

from La Quinta, CA

Comments about Acoustic Lead Guitar Series G100FX 100W 1x12 Guitar Combo Amp:

Out of the box this amp exceeded my expectations. It is lightweight but powerful. I tried it with my acoustic electric and got great sounds. With the chorus/reverb on it got even better. Within minutes, I found a signature sound for a classic song that I have re-arranged. I tried it with my 1-12" Carvin extension speaker and the tones got even better. If you want an amp that is portable, with great tones, lots of power, and great versatility, for the price, you can't do any better than the G100FX. This box rocks!!!

well worth it

By michael dygert

from Hurst, Tx.

Comments about Acoustic Lead Guitar Series G100FX 100W 1x12 Guitar Combo Amp:

I got this amp at Guitar Center because it was at a price that i could not pass up. The price was so low I was expecting to be let down when I played it, but what a nice's a great amp ! It is compact in size but packs a loud 100 watt punch. Has a wide range of tonal quality and the mid shift switch adds presence. And with the dual inputs, one high and one low, it works well when using a mic and guitar combo. I use the high input for my guitar, and the low for my mic and they are almost perfectly balanced. Some amps if both inputs are used will equalize both. But this amp remains high and low.

Great Bang for the Buck

By Bob Knight

from St Paul, MN

Comments about Acoustic Lead Guitar Series G100FX 100W 1x12 Guitar Combo Amp:

Okay, let's get this straight. It's not a tube amp, right? I'm just getting back into amps after many years of being in big bands and going direct. So, in a way, it's all new to me. Again. That said, I went to my local GC to audition amps. Took my trusty FrankenStrat. There's the lineup of amps in that long cabinet, and I took a look at the Bad Cat amp. Nice price, tube, uh-huh. But, just down the row was an Acoustic G100 FX. So, thought I'd plug into it. Had a great time playing through this amp. Plenty loud for club gigs, even at 60w @ 8 ohms. Noticed it even had a little bit of the compression/push-back feel of a tube amp. Not sure how they do that, but, yeah. The guys that worked there came around to check out what I was doing, and had thought I was playing through the Bad Cat. Cool, eh? So, this little solid-state thing sounded pretty good to my ears, and the price point was obviously NOT in the same category as something with valves. I'm not a tube snob - for live work, there are benefits to solid-state. Less delicate, no warm-up, etc. So this is my new go-to amp for studio and stage. Now I will say, an amp like this is not going to sport a high-quality speaker. It just can't at this price point. So I happened to have a couple of Eminence Delta Pro 12s sitting around. Popped one of them into this baby. VERY nice. And all for less than about 4 C-notes, street. What about that 60-watt, 8-ohm thing? Well, I went back and bought one of the Acoustic G35 FX amps, and put the other Delta pro in there. Closed the back with plywood, and put a jack for the speaker, and to the amp. Now I use this as a (sort of) matching extension cab, with the option of hooking the amp back up to the speaker for either stereo use, or as a backup or practice amp. I'm a happy guitar guy. Love these little Acoustic amps - with a little tweaking (and especially if you are a pedalboard user), this is a great setup.

Proud Owner of an Unknown Amp

By Arman Bahraini

from D.C

Comments about Acoustic Lead Guitar Series G100FX 100W 1x12 Guitar Combo Amp:

I never write reviews, but I really feel like people looking at this product would want to know what others think about it. I have to say this is exactly what I was looking for in a single speaker solid state amp! I bought this amp because I wanted a thick, warm, clean sound with little excess noise. Prior to buying this amp, I returned a line 6 spider IV because I felt that the amp was okay but really lacked some definition. I have a great boss distortion pedal, which works well as I expected with this amp. You can get a variety of tones with this amp and it is plenty loud, yet not too heavy in weight, a very simple but effective amp. My only suggestions to acoustic would have been to make the amp a little lower so I could fit it easier into the trunk and also to clean the chorus (delay could be a bit less digital sounding as well, but it might be my stock Ibanez pickups ha). Now quit wasting time reading around and put this amp on your list to try out at the store!

    Comments about Acoustic Lead Guitar Series G100FX 100W 1x12 Guitar Combo Amp:

    I was in need of a loud amp that was not the size of a truck. This amp is that amp. I like that because I have limited space to haul things. I have an amp stand for this amp and it works well on stage and off. I did get mine used. a great amp too. It has a good overdrive channel and the clean channel is great too. It has chorus and reverb built in and you could hook it up to a 410 cab if you need to. It has an effects loop so you can hook up your pedals too. Light weight is another thing I like about this amp. Acoustic makes some great gear and these amps have great tone. Yeah it is not a tube amp but I don't have raodies and those are heavy. Try an Acoustic amp and see if your ears are well pleased as mine. are.

    Worth Looking Into For Sure

    By Scott Vernon

    from Reisterstown MD

    Comments about Acoustic Lead Guitar Series G100FX 100W 1x12 Guitar Combo Amp:

    I bought this amp used and I must say I am very impressed. I will only be using it for rehearsals, but this thing would do just fine in a club setting. The OD is not good (IMO) but the clean channel is SWEET and it receives my pedals VERY well, not to mention it is LOUD and it does not lose tone when turned up. So if your looking for an affordable SS amp I would for sure recommend this little power house..

    Amazing Value

    By Kevin

    from Albuquerque, NM

    Comments about Acoustic Lead Guitar Series G100FX 100W 1x12 Guitar Combo Amp:

    I can't help comparing my purchase of this amplifier in 2014 with my buying a little Peavey practice amp in 1978 (one of the first amplifiers on the market with a "gain" knob). Nominally, I paid the same amount of money for each one, but the G100FX has so many more features, and so much more power, than that old Peavey that it almost boggles my mind. (Moreover, if one adjusts for inflation, what I just paid for the G100FX is about 1/4 of what I paid for the Peavey in 1978.) Kids today have many options for inexpensive but high-quality guitars and amps, and this one ranks with the best in terms of value.

    screw the fender mustang!!!

    By Michael

    from earth

    Comments about Acoustic Lead Guitar Series G100FX 100W 1x12 Guitar Combo Amp:

    I went to my guitar center to get a fender mustang...I played the fender mustang and liked it then I saw this amp and jammed on it a GC while waiting on my friend at the other store and fell in love with it. I've used plenty of amps before and so far this has been the best. It's got good distortion and great effects (Better than my pedals) and it sounds amazing. I still feel funny that it's only a 500 dollar amp because it's worth more in my opinion.
