I've created some profiles of my '68 Marshall Superbass and uploaded them to the Rig Exchange
A few clean, crunchy and overdrive profiles with only amp and 2 profiles with Klon KTR and Maxon SD-9
I've used my '65 Strat to dial in the amp.
Hope you like them
Update March 14th:
I've added 4 extra rigs to Rig Exchange
All 4 are based on my Superbass with settings:
Volume 1: 8
Volume 2: 0
One rigs is the amp without drive/boost pedals.
One rig is with the Mad Professor Underdrive pedal to get a semi clean tone
One rig uses the Klon KTR as boost
The last rig is using the J Rockett Rockaway Archer pedal as drive/eq to create classic rock lead sound
Let me know what you think of these profiles.
