How much did the class cost? I just went to her website and there was no pricing information.This is a good question that depends on what you really want or need on a pedalboard...
When I found out that the UltraWave (Bass) has the graphic and parametric EQ's, HPF/LPF, and Multi-band Compressor the Boss BC-1X was sold off. Then the various distortion and the understanding of the Multi-band aspects along with the Tremolo effects section. I sold a Boss Slicer and have no other dirt pedals. Unless, you consider the dirt also available with the C4 Synthesizer?
The C4 replaced the Spectrum Intelligent Filter because (a) the C4 can preform all of the SIF functions (b) I'm no longer intimidated by the recently updated Nuero Editor 3 UI (c) I took a short class in modular synthesis online (Sarah Belle Reid) that was suggested by a TB member! This got me the terms, how things interact and what to do to achieve a type of sound theory. Also, the Nuero Editor 3 preset library availability and community of contributors.
My desire to have the Nemesis ADT is size, audio quality and flexibility over a super nice Boss RE-202 that has been sold off. The ADT has a "FREEZE" function and the Nemesis ADT can be operated independently as a #1 channel and #2 channel. I will run the C4 loop with #2 channel for modulation not available on the C4. #1 channel will be the entire wet signal for delay. The wet signal runs into the Broughton BBA to clean up/step up the signal into the Two Notes Opus.
Dry (or analog signal) can run from the #2 channel of the UltraWave Bass (direct) to the ZIO Bass Preamp.
(I do have a One Control Crimson Red Bass (DUB) to put after the UWB and can put the really nice Pigtronix Constellator BBD analog delay before the ZIO Bass for a sort slapback delay with one repeat for a Tony Levin trick.)
My answer is at least (2) ~ UltraWave Bass and the C4 Synthesizer.
My current acquisition (ZIO Bass Preamp) also includes the Nuero HUB, now that I will have (3) midi controlled SA pedals.
The SA168 midi adapter is also available for One Series pedals that have the TRRS 1/8" proprietary midi control (HUB) and no 5 DIN connection for midi. ($49)
The SOLEMAN was a must have in my mind. There seemed a best idea to also be using the SA Dual Expression Pedal. I plan to run one side to the Soleman. (The other to the Nemesis ADT that has a 1/4" TRS expression pedal input on the pedal.)
Definitely read some manuals and remember the routing options available. Example: the C4 has an external effects loop connection on #2 channel, but the UltraWave Bass doesn't. The UWB can cascade #1 into #2 channel or run the #1 & #2 channels in parallel.
My board is in transition, but still will feature at the very least a Boss RC-5 Stereo Looper...it may retain the Boss MO-2 Multi Overtones as a stereo splitter and treatment for the dry signal path, but may also go bye-bye, too.
