I've listened to sound clips and my Twreck doesn't seem to have as much gain as ones I have listened to. I'm using a master volume, but I heard a sound clip of one on here with a MV and it had more gain too. Any tips on how to get more gain? Could I try different preamp tubes? Also, the only guitar I have at my disposal right now is a strat. Could the pickups be the culprit. ANy help would be great.

Re: Not enough gain?
What type of MV do you have? If it's the simple voltage-divider type that sits in front of the PI, it necessarily reduces distortion at lower settings because the PI itself doesn't distort (like a Marshall 2204, etc). Are you still hungry for gain when both of your amp's volume controls are maxed?
If it's a post-PI type (like the clip posted here recently), your amp should have plenty of gain at most room volumes. I'd look for a mistake in the components in your preamp.
Pickups to blame? Unlikely, but I'd just borrow another guitar to check, just in case.

Re: Not enough gain?
It is a PPIMV. I guess I'll just go over it again and make sure I have the right values everywhere. Thanks.
Re: Not enough gain?
What version have you built?

Re: Not enough gain?
It's been a while, but I believe it was the a1a version.
Re: Not enough gain?
And now to what version have you been listening? I would think that version A4 may have more gain by looking at the schematic. The main differences are around the 2nd stage.
The guitar you use is also a factor. Single coils have less output than humbuckers and will result in less overall gain.

Re: Not enough gain?
Regarding gain, I found that I had plenty of gain regardless of the pickups that I was using. Naturally the humbucking pickups sounded the best through the amp, but as I have said previously, when I turn the volume fully up with this amp, the humbucking pickup shakes and oscillates in it's mount. Plenty of gain in this design!

Re: Not enough gain?
I'm with Mark - I was astounded how much gain I got (on my semi-Liverpool) with a Tele. Enough for Gary Moore style legato soloing without any stompbox.

Re: Not enough gain?
Why don't you provide more information about your amp. The most helpful diagnostic work I did was to create a voltage chart. Share that with the group and perhaps some chassis pics. Best description I've read of the amp was it is a "flamethrower". That's not far off. Way more gain than my Mesa Mark IV. BTW, you considered your tubes as the source of low gain?
