Been on my desk for 5 days now. Surprisingly well built and calibrated. Even the key tracking of the filter is spot on.
Regarding sound Rob Keeble said:
'Let me explain the design ideas I brought to the B2600. Rather than recreating a 1977 synth with 301 op amps and tired caps, why not try and recreate the 1970 version, as it was originally imagined with high speed and accurate op amps and with matched transistor pairs and the best caps.
ARP did this in the blue marvin but had to compromise component selection to achieve reliable mass production.
So thats what we made with the defects of the original design removed and the precision of the original thinking.
You cant adjust any trimmers to make the sound less tame. The sound is meant to be precise not wobbly not like a KARP, you need to detune the vcos and add some modulation and push the levels into the vcf. Its a world away from a 1977 version..its new. Its about replicating the original 1970 version, and the ideas at ARP when they started out. A blue marvin not a late model, no character has been lost its actually been regained.'
