Am building my a/b set-up (one amp dry and effects in the effects loop in the other amp). figured it'd be easy to choose a pedal or box to split my bass signal into two amps. then the dreaded "tone suck" monster reared its ugly head. picked up a lehle p-split after researching its benefits. plugged my bass into the box and sent the signal into the two amps. immediate tone-suck. i don't want to keep buying box after box trying to see which one doesn't alter the tone. basically, does anyone use a a/b, a+b box or pedal that DOES NOT alter your tone? basic research on other options like the radial jx-2 and the boss ls-2 have varying opinions. oh, and budget-wise, i'd like to keep the price around $150 (if possible). any experiences and opinions are appreciated. thanks y'all!
