Hi - I'm looking for an affordable (not cheap, but thrifty) way to split my signal into two amps. I have an older Yamaha 200w amp - 18" speaker which has awesome low-end, but little definition - and I have a GK Backline 210 which adds great mids and presence, but not enough bass 'oomph'. I'm also running some effects - CEB-3, Overdrive, EQ, etc. - that I would like to isolate to the GK so the bass doesn't get too 'muddy'. Essentially, I'd like to run clean to the 1-18" and dirty to the 2-10. I've been looking at boxes such as the (Nady db-1 or the DOD VAC270, but I'm not sure if this is what I'm looking for. I'm on a bit of a budget (as in, 'under $100') - for now, at least. Any recommendations? Thanks in advance.
