What is it?
Marshall GV-2 Guv’nor Plus. Made in china around early 00’s. Don’t know if there is any official name for this series of pedals, so i’m calling it “Small metal series”.
The original Guv’nor design was a bit of a hit. Not in least due to Gary Moore, who was doing the best promotion possible. Either way, the success of the original unit was little off from questionable. Somehow most folks only reacted to the pedal ten or more years late. I’ll be talking more about the original Guv’nor in a post about original Guv’nor when the time comes. Anyway.
This unit is successor for the original Big Black Guv’nor. With added “Deep” control and a complete redesign, the design team must have had a goal of having the (in)famous tone intact, while modernizing the behavior and sound.
Board design matches the rest of the units in the series with its modern dull traces with autorouted visual feel to them. Otherwise the labor looks fine and this series boxes are well made. Should last your use and abuse for times to come. Schematic appears to be available online. This version of the factory schematic addresses a few issues on the board. First of all, some folks have found the tone stack to be nothing close to their preferences. So there are notes how to match yours to the original, black Guv’nor. And other thing. This addresses a considerable design flaw. There is a 470pF capacitor from after the volume control to ground. I have no idea what the designers were after, but value of 470pF will dump everything that would be called bright to the ground. Meaning that with this cap on board you are bound to lose a lot of highs. Sure. You could swap the cap for something like 47pF to have a way better higher frequency response. But is seems that many people want to omit that cap altogether. And i can’t blame them.
The dual operational amplifiers are once again TL072, manufactured by Texas Instruments. It is not a bad opamp and it surely seems to be a weapon of choice for almost every Marshall pedal. The clipping diodes are in hard clipping configuration, just like found in older Guv’nor version. So there are similarities, while the overall complexity of the circuit here is noticeably higher.
The circuit inside the box is made of three boards. One for the main board, one for controls (which are, no surprise, a 9mm pots with two of them having dual separate sweeps) and one for switching. The hot glue in there doesn’t look that good. Otherwise the build quality is decent.
The controls are your standard three band hi/mid/low for EQ, wich offers nice versatility. Other standard controls are gain and volume. The “Deep” control controls lower mids of the frequency scale from scooped to boosted.
How does it sound?
Certain qualities to the sound are per the original, nowadays a classic Guv’nor. This simply sounds way more muddy and undefined due to that single capacitor noted above. Three band EQ is nice thing to have and it follows the basic principles of the tone controls found in Marshall amplifiers. With the lower mids on a “Deep” knob, the tone controls are very nice and should be enough to please any tweaker. Volume levels are sufficient and the gain range goes from mildly overdriven tone to near massive distortion. But for the muddy and undefined.. You’ll be better of with some other pedal. Or you could just simply snip the C22 cap off the board.
For the price – it is an ok pedal. Not too great, but not that sucky either. One of the worst in the series, but still slightly better than many other manufacturer’s distortion units. Go figure. I don’t see myself using this for anything though.
What pedal do you think sounds in this type of sound and have better construction?
I don’t think there’s anything wrong with the construction. And for the prices these go these day on ebay and other, this might be a nice thing to have…

I have the gv-2 and I been trying severals distortions pedals like crunch box, box of rock, bb preamp, wampler plextortion… and for me its difficult to replace the gv2, that particulary dark & crunch on steroids tone it have, pretty nice for me. Crunch box its similar but more compressed tone and minor low end, I heard crunch box its based on older guv nor. Just I would like to try de OCD. Listen this take with the gv-2 that I recorded> http://www.goear.com/listen/119c7fa/lead-say

I don’t think the removal of the 470pf cap is a good idea.
Here’s an easy mod to make it match the original Guv’nor (courtesy o Joe Simon). Replace these parts:
C12(220nf)->22nf
R12(1kOhm)->10kOhm
R25(470kOhm)->replace with a jumper
R26->remove from board, leave open
R5(22kOhm)->220kOhm
C22(470pf)->47pf
R19(4.7kOhm)->10kOhm
R21(470kOhm)->470kOhm->150kOhm
R9(1mOhm)->220kOhm
C23(22pf)->47pf
D1(1N4004)->2x1N4007
If you have experience with soldering, shouldn’t be too hard, I have personally performed this mod on my pedal. The names of the parts are marked on the board.
As for the diodes (D1) just put them in series, same direction as the original 1N4004.
Here’s Joe’s original video:

hI, IM supernoob, but wanna try this mod. I would like if you show me which specification os each component regard voltage because there are many options to buy.
