The wait is Over, it's HERE!!! Tube tone in a box!!!

By JAVIER bojorquez

from Orange County CA.

Comments about Seymour Duncan SFX-03 Twin Tube Classic Preamp Pedal:

For many years I been extremely frustrated since the only way you could get a nice warm tube tone what ether thru a great preamp or a boutique amp, and eve like that there was flexibility factor, light weight, portable, and pretty much on your finger tips, it didn't exist! but then this pedal come around!!! and for real after so long time of looking this pedal is all of that and more!! of course there are issues, like there is no ON/OFF switch, or that it uses an independent 15 volt power supply, but eve that is insignificant compare to the amazing array of tone you get, I've had the opportunity to be on tour to many award winning artists, and when it comes for them to trust some body to deliver they trust me, for me when it comes to trust somebody to deliver tone and flexibility, I trust this pedal!!! simply a true MASTER PIECE!!!

Suh-weeeeet!!!

By Craig

from Lowell, MA

Comments about Seymour Duncan SFX-03 Twin Tube Classic Preamp Pedal:

This little beauty is essentially a head unit in a little rock-solid box, and it delivers. The tube distortion is powerful, smooth and even when you want it to be, and the lead channel can be made to be so clean, it's like glass. (But you can get a pretty good buzz out of that channel, too, when you feel like you need it). I bought it to solve the broad frequency response of my new under-saddle piezo pickup in my ukulele, in order to recover the full, woody uke-tone in the middle when I'm plugged in. With the separate EQ controls for bass and treble I'm able to get exactly what I'm looking for, and I couldn't be happier. Of course, when I plug this baby into my Gretsch hollow-body, and twist the knobs and the volume way up, the sustain and range of sound it puts out is nothing short of a religious experience. The power requirements for all this necessitate an AC adapter, which I'm finding is a small price to pay for everything this baby delivers, so plan ahead. (I just bring my own little mini power strip for this and my amp and what have you, and I'm also happy to be saving on batteries). With it, I'm getting great sound out of even my little Fender Champ (5W) around the house, but plugged into something more powerful, say, my Fender Blues Junior (customized by Carls Custom Guitars with a dovetailed all-wood cabinet), I'm kicking it HARD, and loving every single minute of it. I could not be more pleased. AWESOME!

Sweet Smooth Power

By George P.

from Utah

Comments about Seymour Duncan SFX-03 Twin Tube Classic Preamp Pedal:

I was seriously considering a new amp purchase until I came across SFX-03. This pedal is amazing! My amp for the past 10 years has been the Fender Hot Rod Deluxe. I thought my sound was good until I tried this pedal. What a difference it makes! To sum it up, this pedal gives an amazinly Sweet, Creamy, Smooth, Crunchy, Power sound. Now my Gibson SG sounds great through my Fender amp!

Look no further

By Anonymous

Comments about Seymour Duncan SFX-03 Twin Tube Classic Preamp Pedal:

This pedal is exactly what I have been looking for for a long time. I got the strat. I got the class A tube amp. Still didn't have the tone I thought should be coming from this stuff. Got the Twin Tube and there it is!! No matter what channel it sings. Roll back the volume and tune in to endless tones. No matter what it is it sounds great through this pedal. Great Value.

evolv owns it

By evolv guitarist recommend

from Philadelphia

Comments about Seymour Duncan SFX-03 Twin Tube Classic Preamp Pedal:

I own this and use the lead channel as my crunch combined with a "boosta grande" pedal to solo when needed. I've combined it with several other pedals and theres been no noise. I love this freaking pedal. It was definately well worth the money and believe me i've spent a lot of money on gear both in my studio and in my band. It sounds awesome! People always compliment the sound. I'm very satisfied!

twin tube

By a silhouette

from h-town, tx

Comments about Seymour Duncan SFX-03 Twin Tube Classic Preamp Pedal:

this pedal is exactly what ive been looking for for years. hands down best overdrive /distortion pedal on the market.i play a gibson sg through a kustom hd100 head and hd100 4x12 cab. its solid state, so i was constantly adjusting to get the right sound and i could never get it. i cant afford a tube head right now so i thought id give this pedal a try. wow! i set it up with channel 1 as a clean channel and 2 as my dirty. i am still blown away. this pedal gave my solid state life! buy this pedal!

Awesome pedal

By Rockin for God

from Birmingham AL

Comments about Seymour Duncan SFX-03 Twin Tube Classic Preamp Pedal:

I got this to use with my solid state combo. I have it running to the clean channel of a 35w peavey envoy 10". The sound is incredible. At first it sounded good, but then after a few minutes of warming up, it sounded great. I can get a medium gain setting on the first channel and a heavy gain on the lead channel. Sounds much better than some of the other Tube pedals that run low voltages.

One of the best

By Funk49er

from Royersford, PA

Comments about Seymour Duncan SFX-03 Twin Tube Classic Preamp Pedal:

This pedal is probably one of the best overdrive/distortion pedals out there. The tone is amazing. It is very easy to use with all the dials you need. I love playing classic rock on this pedal. It captures that sound perfectly. This pedal is however 200 dollars so it isn't cheap. But if you want that classic rock sound and amazing tone, go for it.

SFX -03 Twin Tube

By Jimbo

from Minneapolis, MN

Comments about Seymour Duncan SFX-03 Twin Tube Classic Preamp Pedal:

I recently purchased and spent some quality time with this pedal. I am overall very impressed with it's performance. Since it has true bypass, your amp can be set with a clean or slightly distorted sound and when the pedal is bypassed you get the true sound of your amp coming through. Channel one can be set for a slightly more distorted sound for rhythm and channel two can be set for a higher gain sound for solos (this is how I use it). The channel switching is very versatile and the tone is excellent in every aspect. This pedal sounds like a good tube preamp should. Any sound from clean boost to raging distortion is obtainable. I love the tone of this pedal. The only potential drawback is that this pedal requires a proprietary power supply (not the typical 9 volt supply) and does not use batteries, so do not loose the power supply! It feels solid and substantial, and switches without discernable noise. I also like the "chicken head" knobs for their retro style. I highly recommend this box.
