Buffered effects loop for Brown Note
Hey all, I did a quick scan online and couldn’t find anything specific. I got a pretty good deal on a Brown Note D’lite 22. This one was built by Brown Note and didn’t come with an FX loop. Seems like adding a passive loop will be pretty simple - that’s no real concern. My question - other than a D-lator and Ceriatone solid state pedal options for a buffered loop... are there any other good options to install IN the amp? Kind of seems like a metro/mojotone loop wouldn’t work well which was my first idea. Any suggestions would be welcomed - less boxes to lug around would be fantastic.

A post on the gear page talking about the metro loop in a Fuchs ODS. Not sure if that would apply to all ODS clones.martin manning wrote: ↑Fri Mar 05, 2021 11:37 pmI don't see any reason why a Metro loop wouldn't be a good option.
“ From a brief look at the Zero Loss manual, it appears to be a high voltage FET based effects loop circuit. I have not seen a schematic, but would guess it is similar to the loop circuitry used in some of the more recent Marshalls like the Vintage Modern.
It looks like it should work fine, but there might be one thing to watch. The Dumble style tube power amp normally has lower voltage gain than Marshall power amps, mainly due to the high amount of negative feedback in the Dumble circuit. I'd wonder if the Zero Loss has enough output voltage swing to drive the Dumble power amp properly. This would be a good question for Metropolous. It might also be good to ask Fuchs if his power amp design has the same drive requirements to the phase inverter input as a standard Dumble ODS (Fuchs might have changed it).
Other than the above I see no reason why it couldn't be made to work, but you'll have to be careful selecting a B+ dropping resistor as the voltages in the Traynor might be higher than in the Marshalls mentioned in the Zero Loss manual. Also you shouldn't expect the same tonal differences that you'd get with say a Dumbleator style loop.”
