Kinda crazy - I've been through so many clean boosts, overdrives, etc - like Fulltone OCD, Radial Tonebone Plexitube, Keeley Modded SD-1, TS-9 Reissue, Zvex Box of Rock, Visual Sound Jekyll and Hyde, VS Route 66 - and others, and during that whole time let this thing sit on my shelf in a box.
I bought it in 1996 as a preamp for my acoustic. When I sold that, I forgot about this.
Then I read the HC review about the pedal and got inspired.
Here is my newly found simple set up -
Guitar (1991 Ibanez RG 770 or 2008 Les Paul Standard or 1996 Fender American Stratocaster with Lace Alumitones, or Epiphone Joe Perry Les Paul) ---> Morley Passive Volume --> Marshall JCM 800 2205 with Outlaw Chorus and the DOD FX10 in the effects loop.
This pedal in the effects loop gives the sound massive heft. I probably needed to go through all of the overdrive pedals to learn my lesson, and now I did. This this is outstanding.
It is quiet and provides no coloration to your tone - just up to a 20db boost of pure clean power.
Reliability/Durability:
I will not be using this to boost solos - I'm the rhythm guy in my band - so it will be on full time. I am expecting to not worry about the switch, although I can understand how people might.
The casing is die cast metal and sturdy - the internal components inside look find (but I'm no electronics guy). I do like the feel of the knobs - substantial - slow and heavy.
Ease of Use:
Can't say it's the simplest pedal ever because it has two knobs, not just one...that said, this will not require endless hours of tweaks. Just "Tone" and "Level"
It is amazingly simple to get good tone out of it.
