waynepunkdude Posted September 14, 2009 Share Posted September 14, 2009 (edited) I get my Ampeg back and I want a switchable pre-amp my idea is to go Bass -> Boss AB2 (A) DHA EQ-DI -> Pre-amp in ( B ) Amp input Therefore having two seperate pre-amps, will this work? orcan I cause damage?

coasterbass Posted September 15, 2009 Share Posted September 15, 2009 Not sure about the line level etc, but one thing to consider is that the Boss A/B box might create 1) some earth hum, 2) you can get minor phasing issues when running the two amps at the same time which would cancel out your tone (running just A/B is fine, just if you are running 'Y') Dedicated amp splitters like the Tonebone have isolated power supplies and a ground lift just in case. In terms of the wiring with the Ampeg, my only concern would be that by having a jack permanently inserted into the Amp B input it would 'override' any normal input into the main jack. So you'd be switching from DHA to DHA muted. Again, its just something to consider. Quote Link to comment Share on other sites More sharing options...
waynepunkdude Posted September 15, 2009 Author Share Posted September 15, 2009 (edited) Might be worth getting a Y cable and using the DHA as a boost/cut? So Bass to AB2 (a) Amp input (B ) DHA -> amp input Edited September 15, 2009 by waynepunkdude Quote Link to comment Share on other sites More sharing options...
WarPig Posted September 15, 2009 Share Posted September 15, 2009 (edited) How about: Bass > AB2 (A) Amp Input (B ) DHA > Effects Loop Return?
