stage center reverb pointers

[gharukaza]

Greetings one and all!

I've just finished successfully putting together the GGG stage center reverb circuit on my breadboard. It's my first pedal attempt and it works beautifully so I spent the afternoon doing a dance of joy. I've now stopped dancing and I figure I should probably tweak some of the components as I am getting a bit of distortion when I play loud. From what I gather the original schematic is for an Accutronics tank with 310Ohm input impedance, whereas mine has an input impedance of 190Ohm, so I guess I should start with adapting for that.

I realise this is a popular pedal so there's a good chance this has been asked before, I'd be grateful if anyone could point me in the right direction.

Also: could anyone suggest some exciting mods to the project?

Thanks a lot,

Thom (from Malta!)
