I'm using my HD500 with the 4cm to use my amp's preamp for high-gain sounds, and the HD500 for overdrive sounds, clean sounds, and all effects. I'm then using my amp's power amp and cabinet for reinforcement.
Here's the trouble: I get my clean (Blackface Vibrato, full amp) patch sounding just the way I want, and max the channel volume (it's the quietest patch). Then I adjust my OD patch (PhD Motorway, full amp) to match the Blackface. Now I adjust my amp's preamp to get its level to match the clean and od patches- by dropping the preamp volume/master volulme. Doing this, I'm getting a lot fewer dB's at the speaker than I would get if I was running my amp without the HD500, there's so much volume drop that I'm having trouble getting back up to rehearsal/gig volume, even with the HD500's Master maxed.
- The amp is a Genz Benz El Diablo 60TS head, which has a serial, post-master FX loop. GB's documentation is unclear if this loop runs at +4dBu or -10dBv.
- I run the HD500 FX loop in "line" mode, with a -7dB send and a +8dB return, per perapera's research. [Updated Link]
- Before using the HD500, keeping the amp's channel volume at about 50% and the master volume at about 30-40%, I was able to get good rehearsal/gig volume.
- I'm matching patch levels using the HD500's looper (pre-processing) and an iPhone dB meter at bedroom and rehearsal volumes.
Solutions I've tried:
- Running an Xotic EP-booster (maxed, for about +20dB boost) between the HD500's output and the amp's FX return. This provided adequate levels, but I prefer to use the EP-booster before the HD500 (not maxed).
- Using the "Tube Comp" model after my clean and OD amp models. This provides adequate levels, but I'm unsatisfied with its effects on the clean patch's tone.
TL;DR version- My clean patches aren't loud enough to drive my power amp to rehearsal/gig volumes.
Does anyone have advice on getting a squeaky-clean patch to match the level of a physical high-gain preamp? (no, I'm not interested in a new amp or a frfr solution)
