Hi all!

Enter Infinity, a guitar preamp offering great sound versatility, from clean to heavy distortion. It can be used for DI applications (in conjuction with the PA and a monitor), and for recording. A short presentation can be downloaded here.



Samples
A Youtube video of first prototype, and containing some samples (direct recording to the PC soundcard): Here!
Other samples:
- Here! for a Vox style.
- Here! for Pink Floyd's Comfortably Numb (delay was added through Audacity).
- Here! for "Two minutes to 2h in the morning" (since I recorded it at 2AM), Iron Maiden style.
- Here! for a Plexi style.
- Here! for "Thunderstruck", AC/DC style
- Here! for "Sharp Dressed Man", ZZ Top style.

Hi all!

I am new to this forum (and a tad more experienced in DIY, but not that much).
My current project is to build an LXH2 preamp (both with Fender and Marshall sims).
Schematics are here: http://home3.netcarrier.com/~lxh2/

I tested the 1st one on, well ..., my testing board.

Messy, but it sounds tasteful, and has surprisingly almost no noise (sometimes it oscillates a bit, which I think is due to a badly linked ground somewhere).

My question is about powering the circuit. I am using a 200mA 9V DC regulated PS, and I get a +/-9V voltage using the circuit on Geofex ( http://www.geofex.com/ - in the circuit sweepings section). This is just for test purposes, and I don't know whether it'll be able to power both the Fender and Marshall sims ... my multimeter is dead, so I can't check current consumption! But it is surely a simple circuit, and safe too.
Would it be better to replace it with a more 'consistent' power supply?
Is it possible to build a PS with a transformer and rectifier diodes / filtering on veroboard or perfboard, or would the current in the tracks be too 'strong', making them and components too hot? (I can't make any PCBs at home, and there are no shops in the city who do it).

Thanks !

(BTW, sorry about my English, I'm still learning ...)
