[sdiy] Rising "Realsitic Electronic Reverb" prices and the urge tomodify...

[harrybissell at wowway.com]

Its funny to me how products that I thought, well... er...
well it HAS got a BBD in it (if you catch my drift)...

were not too viable, have become loved and wanted. Its not just the
RatShack electronic reverb (which I did buy and build)... but also
EH Electric Mistress (which I did NOT buy as I thought it sucked..)

I guess there is no accounting for taste. If you love 'lo-fi' the
Radio Shack reverb has it in spades...
