Where would you put the buffer pedal in this config?

Thanks Peegoo, it'll be open for experimentation I suppose. I had the trem before delay/reverb but found that it seemed to mask the reverb. I also had the OD's stacked low gain to higher gain but saw references to stack them the other way around. I'm not 100% sure the volume pedal is even gonna stay on the board because its seems to be more of a gigging convenience than a goober playing at home. My BIL gave me his old Morley pedal and I figured I'd put it to use.

Boy, have I crawled down the pedal bunnyhole. I'm seeing folks stating to put a buffer at the beginning AND end of the chain. I'll need a bigger pedal board and power supply to do that, so...no.

There is not a lot of info on the J.Rockett unit, but for $50 I figured it was worth a shot. Being that it also works as a boost and can have the buffer part disabled by an internal dipswitch, I'll give it a go.

All I can add is plug them all in and make sure you're satisfied before mounting them on your board.

As you’re not using a vintage type treble booster, wah or fuzz, I suggest to make the buffer the first thing the guitar plugs into.

Bear in mind that the Morley volume pedal may not be true bypass, and works using an optically controlled circuit rather than a pot, so it may already have a buffered input and output.

I don’t see the benefit of the true bypass thing, especially for multi pedal boards; all those pedal to pedal interconnects, and the switching wiring inside each pedal, will add to the capacitive loading on the guitar, muffling its tone. So the net effect of the board will not be transparent, in regard of its effect on the guitar signal.

Conversely, my Crybaby wah sounds much better since I removed its input buffer and made it true bypass. In that case, the loading effect on the guitar of the lowish input impedance has a beneficial effect on the resulting wah tone, in the ‘toe down’ setting. Clearly, it has to be positioned early in the signal path, prior to any non true bypass buffered pedals.

My two cents: Peegoo's point is a very good consideration if you find that the sweep of the volume pedal changes depending on what OD/boost pedals before it are switched on or off. If that's not an issue, then like Rob said you have no fuzz or vintage low input impedance gear that would react badly to a buffer up front, so I would put the buffer immediately before or after the tuner (doesn;t really matter which you choose).

The HoF is an excellent buffer at the end of the chain when in trails mode. That gives you good signal drive over long cable runs to the amp without degradation of high end loss, at least when the tremolo is off. (I don't know what the JHS output buffer is like but trem after reverb is how the vintage Fender blackpanel amps are built, so I'd probably do that too). If you run the trem in front of the HoF in buffered mode, you will always have strong consistent tone to the amp no matter what length cable you run, ya know for those times we're on a 300ft wide stage. :-)

Ah yes, that seems to be true. The mini is mono only, true bypass only.

Polytune 3 does (switchable), other versions do not.

Ok, before the tuner gets my vote then.
I’m not up to speed with the current pedal market, but I suspect Boss are still a pretty big player and aren’t true bypass.

So all three pedals arrived. Initial impression is:

The Rockett Steampunk seems to do its job as a buffer at the first position. Engaged in the boost mode it offers a ton of extra oomph. 👍

The MXR micro chorus does its thing. There's 1 knob with no ability to adjust the amount of chorus, only the speed. I've read it elsewhere and can confirm, engaged it bumps the signal noticeably. It'll work fine if I ever find myself playing BADGE or Brass in Pocket.

There seems to be a lot of overlap between the Euphoria and Timmy. I may switch the 2 around. The Euphoria has a ton of clean headroom in the open mode and under 18v power.

It's taken half a century, but I finally got my pedalboard config'd, lol.

It’s that great speaker in the PRII. 😜

It can change month to month or year to year. I naturally think of low to high gain but I try not to get too hung up on it. Sometimes I'll swap which pedal should take which role, e.g. maybe the SL drive would function better at a lower gain, earlier in the chain. Also, because I'm running into a clean amp, maybe the lowest gain pedal is my "edge of breakup" tone and may work better at the end of the chain getting pushed by the higher gain pedals, rather than at the front. Also I never have three OD pedals on at a time, just two. There are two reasons for that: first, it never sounds a good with three pedals; and second, I can hit two pedals simultaneously with one foot but never three! So I often arrange OD pedals in pairs that work well together rather than strictly by gain.
