Title: V30 speaker simulator
Post by: KMG on January 28, 2011, 06:53:18 AM
For use with single or dual supply & additional possibility to use "-" or "+" of power supply as reference ground with single polarity supplying.
Construction allows you to add it to existing design simply by drilling hole for the output jack.

Congratulations on your new project, very well made. :tu: :tu:
One small doubt only about the mixed (Laney style) through hole + SMT components.
I guess it will make things a little more difficult for the average home hobbyist.
As a side comment, the single/double PSU option is really useful. :tu:
Thanks again.

Looks very interesting :) do you maybe have a sound sample?
I've been meaning to build a speaker-sim for some time now, I just might give this a try!

There you can compare reamping samples recorded via 4x12 cabinet & V30 simulator:

Thanx!

I've seen the ENGL thread, but somehow missed the V30 simulator :loco ;D
