highly specific stereo trem quest

[Errant Tiger]

I'm trying to find a stereo trem that has the capability to go from full stereo to wet/dry (i.e., trem on one side, dry on the other) with the mere tap of a switch or expression pedal. I'm open to using presets to achieve this but not if I have to press and hold or double tap or scroll whatever - I want to be able to kick this on and off.

So far the only potentials I've found - but haven't confirmed - are

EHX Super Pulsar
Flux Effects Liquid Tremolo
Boss MD-500

Any ideas, O wise ones of ILF?

Those are indeed all tremolo pedals with stereo modulation. The thing with what you're looking for though is that it happens at the output stage and I can't think of any pedal that lets you switch output modes with a button. Usually you do it by physically plugging/unplugging an output cable, or by selecting a menu option (the RV-500 lets you do this in the System menu, but I see the MD-500 does not). With the menu button thing you'd need it to have MIDI and to have something to send a program change to, if indeed that's one of the functions the particular unit lets you PC.

I think the best way to do it would be some kind of creative use a stereo line selector. I'm not sure if the Boss LS-2 does it but that's where I'd look first.

Thanks for the response! While none of those pedals specifically offers the function I want, I'm wondering if they have workarounds. For example, the Pulsar's manual says

"STEREO IN / MONO OUT or STEREO OUT Setup: The RT. PHASE knob adjusts the amount of the Right input that is output from Left output and the amount of Left input that is output from the Right output. At 0° the Right input comes out the Right output only and Left input comes out Left output only. Set RT. PHASE to 180° and you will hear an equal mix of Left input at the Right output and Right input at the Left output. Turning the knob all the way up to 360° will reverse the input/output channels completely so that the Right channel is only output from the Left output and Left channel is only output from the Right output. The modulation waveforms are normally in phase with each other but if you enable the WAVE INVERT button, the right channel’s modulation waveform will be inverted as compared to the left channel. When DEPTH = 0, turning RT. PHASE, or sweeping with an Exp. Pedal, will allow the two inputs to cross-fade between the two outputs."

and I wonder if that would do it. Likewise, the wet/dry mix of the Flux ranges from 3 dB to 30 dB, and via expression pedal the depth can be ramped up to 40 dB, if I'm reading the description properly. So I wonder if that might do more or less what I want, though I think it seems like a longshot.

Can you point me to where you read that about the MD-500? I can't seem to find it anywhere.

This is all because I'm trying to replicate the sound of jumpering channels on my soon-to-be-gone Ampeg Gemini, and running the trem channel at a lower volume, to get an underlying pulse kind of sound. My current trem situation is a Behringer FX600 going out (through two separate mono verb pedals) to two Boss Katana 50s, which of course have plenty of trem, but stupidly cannot be controlled via footswitch. I suppose I could just add in a mono trem pedal after the Behringer; even though that seems silly (since trem is not an effect I particularly use that much to begin with), it might be the most direct route to what I want to do. I am so bad at signal path stuff that I get fits just contemplating a line selector type thing...

Poly Beebo will 100% do what you're describing, but it's not cheap.

Cheapest solution is hook one channel of any true stereo trem up with a bypass looper to go wet/dry on only that channel
Left: ->trem left channel->
Right: ->loop in->loop send->trem right channel->loop return->

twas the MD-500 manual, but my bad, it looks like MD-500's output mode is located in the BANK section where you set up your Simul Mode settings (RV-500's output mode is located in SYSTEM so that's where I presumed it would be). Page 23: https://static.roland.com/assets/media/ ... ng01_W.pdf

So you could set up two Prime P trem patches for both A and B with identical settings (or not, fuck the system) in parallel simul mode, set the output mode to A/B, which makes your A patch goes through the left output and the B patch goes through your right output. Then set the footswitches so that you can turn the A or B patch off individually.

If you don't need the stereo movement and just want trem in both amps and then in just one via footswitch, do what backwardsvoyager said with any trem you already have.

Thanks to all of you! This has been incredibly helpful. I think the first thing I'm going to do is dig up my Southampton Utility Knife and throw it on the board after the Behringer and see if this is really what I need. Silly that I haven't done that yet, but I totally forgot I even had that pedal. If I absolutely can't live without stereo/mono trem options, I guess I'll pick up an MD-500. And if it turns out that I really only need stereo, I think I'll pick up a Super Pulsar, because in my researches I have really become intrigued by it... seriously, thanks again.

Oh if you have a second trem, you can route the outputs of each to their own amp, and turn off one of them when you want trem in one amp but not the other.

I've been experimenting with this for the last 24 hours and I have come to the conclusion that matching up trems is a pain in the ass, and that stereo trem is more important to me than wet/dry trem, so I'm either going to pick up a Source Audio Vertigo or (if I'm feeling ambitious) a Super Pulsar and just live in stereo.

[friendship]

Hell yeah. Super pulsar's phase chicanery looks dope as hell, I bet using the expression or envelope to modulate it through two amps gets real cool real fast.

(though while you're waiting for your new tremolo pedal, try this trick for fun: set each of your trems to a funky rate ratio, like have one doing quarter note throbs and the other doing triplet throbs wubwubwubwubwubuwbwbwwbs)

Katana 50 DOES let you change amp patches by footswitch (have one).

Set one up with the A being trem "on", the B identical but with..no trem.

Or whatever light % mix on Trem B you want.

Problem solved?

How in the fuck did this not occur to me? I guess probably because I have not gone into the editor since I installed Sneaky Amps on week 1 of my first Katana.

THANK YOU.

Update: I got overwhelmed and bought a Vertigo and called it a day. The Vertigo is fantastic and I don't miss the functionality I was chasing. I appreciate all the input!

[Dandolin]

Vertigo seems a deal, and nicely compact. I personally am not bothered by the Neuro app - can the Vertigo get into Goatkeeper territory? It looks like the trem stuff on the newest Multiwave can?, so I would tend to think it can....

[Errant Tiger]

I haven’t even touched the app yet - I’m sure I will at some point but who knows when. Compactness and not having to do too much Tetris on the board was a big factor (as well as the price). I have no idea what it’s fully capable of yet…
