Are there any issues with running 2 preamp pedals(MXR Bass DI+ & B7K) in combination with a Genz Benz GBE1200 Head? And would it be more beneficial to replace my head with a power amp if I'm running those?
I have 7 preamp pedals, and run them on their own or in conjunction. If it sounds good, then it is.....
stacking preamp pedals can give some nice results. my current favourite is the Dave Hall VT1-EQ into the Behringer Sansamp clone.
I run 4 pedal preamps and 2 rack preamps, going into my power amp. Some mix well together, some get a bit unruly when stacked. No issue with running multiple ones.
Yup I pre-drive both the Microbass II on my board and the BMAX in my rack with a BDDI all the time. Or I run them in parallel. Like nshuman said, some combos work nicely. They really aren't being preamps when running close to unity gain anyway.
I have the pre in my active basses (fender zone and a spector legend classic pro 5) as well as the sansamp GT2 and then the pres in my heads (2 trace elliot heads) sounds fine live and records great.
