NoirBass

These are great when used like a Sansamp.

Ok, so just rigged mine up - unfortunately I'm getting the same issue as you describe! The middle switch position is noisy and the top position is worse. I'm using an isolated Strymon PSU. Out of curiosity I A/B'd it with a Boss CEB-3, Tech21 Bass Boost Chorus and an EHX Bass Clone. The Boss and the Tech21 were all but silent. The EHX was noisy (top end hiss) as soon as I engaged the effect. The Providence was nice a quiet in the bottom switch position and progressively noisier (hiss as the LFO sweeps) as you went up between the three positions. I can only assume the Tech 21 and Boss have some filtering going on before the output? I also added a TU-3 in before the Anadime to see if it needed buffering to stop the hiss - it made no difference. I must have noticed this before and just settled on using the bottom switch setting? It's a shame as out of the four pedals the Providence has by far the best sounding chorus to my ears.

The leak was correct!

Hey, I’ve got the Anadime BC. Let me check it out. I would say Bagmans suggestion above is a good place to start

You could well be correct, but my understanding is that as long as it’s daisy chained (as the RPW-7 is internally) it will work correctly: Powering Options ACA 12V DC Adapter: Use a dedicated 12V DC (center-negative) adapter or a power supply with a selectable 12V output. Battery: A 9V battery will provide the correct 9V internally, bypassing the voltage-dropping components. Daisy Chain (with a PSA pedal): If connected in a daisy chain with at least one standard 9V PSA pedal, the ACA pedal's internal resistor/diode circuit is bypassed, allowing it to run correctly on 9V When powering ACA Boss pedals I’m always lead by the brightness of the LED. Setting them up as I did in this test gives full bright LED’s so I’m assuming they are working correctly. That said I do have a 12V Boss ACA PSU and I’ll A/B and update.

OC-2 Comparison.mp3 Ok, so I've plugged in The OC-5, followed by an '85 'Octave' OC-2 and then an '83 "Octaver' OC-2. All are soloed on the -1 octave (OC-5 in vintage setting on Bass mode) All three are individually powered by a Boss RPW-7 to make sure they all have the correct voltage hitting them. I'm using an MIJ '57 Reissue P bass with worn in flats, tone on full, straight out of the DI of an Ampeg PF800 pre EQ into Logic no processing. Playing around the sweet spot of 7th to 12th fret for the little riff in the demo. I can't feel or perceive any latency from the OC-5, what I can hear is that they all sound a bit different and the OC-5 is much louder due to a better noise floor.

I do, let me plug them in and see what my thoughts are. My gut says that I prefer the OC-2 as that’s just what I tend to grab if I need an octave. I should also add that I have a few OC-2’s and my favourite is an ‘83 Octaver. So they do vary a bit.

Just noticed this, even Boss don’t have it on their site? https://ebay.us/m/OM14N5
