You could always try a gainclone

I *could*, but I rather like the look of something like this:

'cos I suspect it has more chance of *really* sounding good, rather than
being based around a chip being used for other than its designed purpose!
(ducks down behind 0.2C/W heatsinks to hide from gaincloners hurling
flaming 1000uF capacitors...)

Well you could try this then

I didn't see the need as the one I built was being fed by a valve stage
anyway. They are fun things, I was quite shocked just how good they are
for £30. Of course you could go to the other extreme.
