simply awesome

By scott saxon

from Mobile,AL

an earlier review I think said "Randy Rhoades type of sound".this is true,also gets a great Rush and Tool type of sound.has a very versatile tone knob.makes my solid state ibanez GX-100 scream like a marshall.I tried every dist pedal out that guitar center has on a line 6 amp.this pedal was by far the best.If you dont think this pedal is heavy enough,then deltalab metal dist is next step,which I also tried out and is awsome but has more gain than I need.I love this pedal!

This Is It!

By Joe Bass

from St.Louis, Mo.

I wanted a transparent great sounding distortion and tried one of these sight unseen and sound unheard. I am not disappointed. It works very well with my old Thomas Crybaby as well. I will certainly consider Deltalab in the future should I decide to replace some of my other effects.

Great Distortion

By mike

from Ohio

This is a truly good little distortion pedal. I wanted a little extra oomph on my natural OD on my fender tube. This thing goes from late Zeppelin, Black Sabbath etc, all the way to a sorta like metallica sound. It is also true bypass which is great. If you need a pedal for distortion that won't color your tone when its off, this is it.

Real value for the money here

By Dave

from Tenecula Calif.

I picked this pedal up a few months ago not thinking too much about it, I was just going to throw it in the collection. I thought it looked kinda cool and had the cash on me at the time. What I did not know was that all these months later the RD1 would still be on my pedalboard. The bottom line is .. it just sounds too good not to have it there. It sits along side an Xotic BB, Fulltone OCD (version 1) a Barber LTD Silver, Frantone Peachfuzz, Digitec HardWire tube drive, DeltaLab TO1, MXR Fullbore and Danelectro CoolCat CO1. I have lots of other (nice)distortions and overdrives that I switch in and out when I need them. It may seem a bit excessive but I do tone stacking often using 2,3 or even 4 drive pedals to get a particular sound (for recording.) Everything about the DeltaLab pedals impress me and because I liked the RD1 so much I went ahead and purchased the green overdrive unit too..(another killer pedal!) I love them both. The RD1 is more gainy and has a bit more bass and (hair) to the tone, a bit more compressed too. It has more of a Marshall type of thing going on. I play through an EL84 based tube amp and play a hot rodded strat with EMG SA pickups. This pedal has better features than a lot of my more pricy pedals. True bypass, nice rubber bottom pad, cool pyramid LED and the power in is up on the top of the pedal out of the way of the guitars input and output. The pedal has some weight to it also so it does not feel cheap in any way. The battery access is way better than most of my other pedals. The pedal is quiet although I generally do not run the gain past half way. It also interacts very well with all the other pedals I own and not surprisingly it stacks real well with its green colored brother! I feel right now at this particular time as messed up as the ecomomy is it is a great time for pedals. True bybass is becoming the standard and I am getting way better tones out of more reasonably priced products lately, I think the build quality is better too. What we are buying today just may be the desired classics of the future. The RD1 sounds great looks good and has a nice feature set (the tone knob is actually voiced correctly and does somthing!) I have 40 years of guitar playing backing me up on this one! The RD1 and TO1 kicked a Fulltone GT500 off my board pedalboard and I havn't looked back yet!

Tube amp in a box

By Mikey

from Hippy town

This pedal is a joke when it comes to sound possiblites. I have a raven 20 watt with a Epi Les Paul and i love blues, and i wasn't really happy with the gain on the amp so i got this. WOW!!!!!!!! when dialed in just the right way you can get a Line 6 HD tube amp sound out of it. It goes amazing with strats and les pauls but aside this can dial in just the right sounds for blues to hard rock to straight up metal. One draw back i would say it that it does eat up battery life but hey its worth a daisy chain power supply.

Deltalab RD 1 distortion pedal

By Charlie

from boston

this is a good distortion with only two problems 1. it is pretty hard to get the settings you want with this, i can never seem to tweak it just so 2. the battery life is very short, i ussually need a new battery every week (i have an ac adaptor now, much needed with this product) those are really the only two problems with this, if u are looking for a good distortion pedal go with this but if i had the choice i would go for the Boss.

Tube in a box?

By Mikeytheripper

from Eugene Oregon

I own this pedal and i play metallica, BFMV, COB, Skid row anyways this little sweetheart is my bestfriend in my pedal board. I use a Boss MD-Zone pedal, a digitech grunge pedal, this and a boss DS-1 pedal and with this pedal when i'm screamin with harmonixs or soloing till i break a string this pedal gives the Metal Zone pedal a kick right where it needs it, not only does it give out a sweet tube like distortion but it also allows full color control of my guitars pickup. I wouldn't trade this even for a Tube Screamer. I love driving my amp to its limit and this does it. one draw back i have to say is it will short your other pedals but tinker and it'll give you some sweet gain boost! Rock on

Great for Punk and Rock!

By Jake

from Chicago, Illinois

I've been playing for a little under a year now, and i picked this pedal up because it looked like it could take a beating, and it defiantly can! I've dropped it down the stairs, side walk, its been dropped in a puddle halfwawy up its body, and even feel out of the car, but it still holds up! It has perfect control, you can set your gain perfectly for Green Day's "Brain Stew" or anything off of "American Idiot" It can match Ozzy Ozbourne's "Crazy Train", and even a slight little distortion for "East Jesus Nowhere" I use it with my Stagg 40 Watt amp, and an Epiphone Les Paul Deluxe. I highly recommend it!
