Thanks guys for a very quick response and suggestions.
I use a lot of effects on the HD aswell so would always use that rather than just 8 amps in the DT.
Hi - Is the Firmware update v2.0 necessary if using an HD500 with the DT25 amp? I don't want the expense of MIDI cables and the extra work involved if I get everything through the HD 500 anyway. Cheers.
