Ok tried the Ampeg SCR-DI and it’s very nice, I like it.
Tried it with Ampeg Opto Compressor in front and after and it sounds better with compressor after especially as I use my compressor to tame the input into the ABM600
Will be fitting on to my Pedaltrain so I’ve removed the rubber feet screws and replaced with flush screws.
Hadnt considered the access to the DI connection ( for occasional use perhaps ) so I will space them apart.
Dual lock on its way so I can make a good job of it.
The tone / EQ ( pretty much as suggested ) sounds very much like Ampeg
The depth of sound with Ultra Low in sounds full and good with a pick more so than the Shape ON sound on the ABM head.
I can now use both the ABM600 and my Orange LBT and still sound the same !!
Highly recommended pedal and less than buying an Ampeg amp !
