Yes fair enough.

So you mean that when you do that (route Sub to PA), you no longer get the decrease in overall volume when you (only) bring up the Octave knob (as I describe)? My issue isn't getting the Meatbox boomy Sub sound - I can - it's how each of the knobs behave individually that I find enigmatic. Having spoken to Digitech (who owns them), this is because the knobs are coupled, not independent. Thanks all.

Oh, just that deep woolly booming bass, characteristic of the Meatbox. I'd have liked to it be a bit more intuitive! Sucking volume when I turn up Octave is absurd to me - no mention of it in the manual / web page. Having to add Sub to get virtually any octave seems futile. The Octave and Sub knobs might as well be combined into a single knob. I can't even tell whether Octave is any different from Sub (is Sub 2 octaves down?). With Octave at 3pm and Sub at zero, I have virtually no octave. I need to bring Sub to 3pm to get decent octave, hence my comment re combining the 2 knobs. Finally, to basically get the woolly booming bass, I have all 3 knobs at 4pm. Might as well have just one knob. I'm quite disappointed at it's versatility and lack of intuitive controls. I'll play with it a bit more but I suspect it's not going to stay in my gear. For recording, for example, a sub-synth plug-in will do the same.

Hey thanks. The 2 amps thing is a good idea, although I'd like not to have to do that. Headroom comment noted too. I'd have loved to get hold of a Mantis but they're tough to come by in the UK. Seen lots of vids & comments re potential gear damage so I'm at low volumes at this stage.

May II seek a little knowledge from seasoned DOD Meatbox users please. I just bought a brand new DOD Meatbox. First thing I do is match the volume & timbre of the affected signal (effect on), to that of the unaffected clean tone (effect off). Playing through a Trace AH350SMX I've had new since the early 1990's (onboard effects off / flat). Octave & Sub knobs fully CCW, Output at 2pm, Low at 3:30pm. Volume match exactly, timbre not quite but pretty good. Now to add some octave down, I bring up the Octave knob to 2pm, the octave down is heard, but the overall output volume (perceived) goes DOWN! Quite a BIT! As though the octave sucks the original signal. Is that normal? Is it the aim? Does the Output knob lset the output volume no-matter-what (regardless of other controls) thereby sucking clean tone when Octave is added? (perhaps for speaker-safety?). Some volume returns if I then bring up Sub to midday, but I don't want to on this occasion. I also find it a bit noisy. The Trace has a little hum, but significanly more with the Meatbox (which I'm powering from a Strymon Ojai with no other pedals). What's going on? Thanks

Main heads: Eden WT-550B (2 Ohm version), Ampeg SVT-III Pro + SVP-CL Preamp, Trace Elliot AH300SMX, Aguilar TH-500, Markbass TTE-500. Also a little GK MBE150E-III head for quiet gigs. Main cabs: Hartke 2 x HL210 & HL115 (with Eden, Ampeg, Trace, Markbass), Aguilar 2 x SL112 (with the TH-500). I'll consolidate one of these days when I need to focus on 1 or 2 particular bands...

Thankyou again.

Does the 4.8VA (units of Watts) matter?

Interesting. Thanks

Thanks everyone. Super useful. Case closed.
