I've read that the pre-amps in HD500 are the best to use with DT50 and DT25, so I've put a setlist together with all of the pres as a baseline for my patch creation. The problem I encountered was that the volumes varied WILDLY and I kept blowing up my ears going from the quietest amp (Hiway-100 apparently) and a Treadplate for example. Of course one amp is louder than the other, but for home use, or testing, having these patches be leveled is a must
So I've gone through and leveled out (with the MIXER setting) all 30 of the pre amps to be very roughly the same loudness. There is definitely some variance. If anyone cares to correct them more properly, please do so and post the update.
In this setlist, Hiway-100 is the quietest amp- I have the db setting on the mixer maxed, so I used that setting as the baseline for loudness of all the other amps. Very unscientific, but now I don't get ringing ears if I'm switching between.
Hope this helps.
