A friend at work who does a lot of guitar playing asked me the other day if it would be possible to just make the output section of a tube guitar amp. The reason he asked is that a lot of the effects boxes he has apparently cover the pre-amping and overdriving pretty well, but of course, they won't drive speakers. His question was also inspired by the Mesa Boogie 20-20 (http://www.mesaboogie.com/Product_Info/ ... tereo.html), which fits the bill nicely, but is kind of expensive.
It seems fairly straightforward to just feed the effects box to the output section of an EL-84 PP Amp. Would it make sense to have the input through an isolation/matching transformer? Other considerations?
thanks in advance,
