Hi guys! Recently just purchased a HX Stomp after years of thought (I know I'm late to the party). I am extremely impressed with the unit and all that it can do. I am currently using the HX stomp in 4 situations:
1) Stereo with amp and IR blocks
2) Mono with amp and IR block
3) Stereo into an amp, using HX stomp as an effects unit
4) Mono into an amp, using HX stomp as an effects unit
The amp with IRs sounds amazing. Different FOH engineers haven't said anything bad other than it being bright (which is tweakable since I just got it). However, I recently just used it as an effects unit running into the front end of an amp (HiWatt head connected to FOH through a Palmer PDI-03) and I'm pretty disappointed with how it sounded. In my ears, the HX stomp seems to have cut much of my low end and replaced it what sounded like a guitar running into a DI. I ran instrument level into the amp and had my input impedance set at 230K.
Is there anything I'm doing wrong? Does it have anything to do with the amp running through a Palmer?
