Same for me. Left 2 messages for customer support and emailed them and have had no response. SweetWater replaced not 1, not 2, but THREE EHX Tri-Parallel Mixers and everyone of them do the exact same thing.

I sensed that unplugging the power supply from the pedal would cause undo wear on the power port so I installed a small power strip on my board and when I power my board up the Tri-Parallel is not yet turned on. I can then do my factory reset by holding down channel 1 & 3 while turning the dedicated strip on.

On my first replacement (2 replacements ago), holding down 1 & 3 wouldn’t work. I had to hold down all 3. The last 2 replacements I’m able to hold down just 1 & 3.

I really like what the mixer does, but my concern is that the issue will propagate and the pedal will become entirely unusable right about the time when the warranty expires.

My disappointment in EHX Customer Support is profound. They don’t care. Simply put. They don’t return emails to customer support. They don’t return phone calls. They are non-existent.

SweetWater is great, but all they can do is replace one faulty unit with another faulty unit. Their support only test the pedal for a very short period of time and not on an actual board that will be “lived in” day after day. They get a unit, plug a couple pedals into it & fire it up and if it doesn’t happen, they consider me an idiot and report back “we can’t replicate the issue”.

I’ve provided a picture Of my board. My board is powered by a Strymon Zuma with a Strymon Ojai R30 Expansion Kit. My Joyo Power Tuner (Don’t laugh, it’s a handy little guy) has two 500 MA slots that I power a cheap EQ Pedal and an ISP Decimator X with.

My chain is: Fender Level Set Buffer with a dedicated output out to the tuner, then the chain output goes to the Compressor “in” of a TrueTone Route 66 V3 > Out of the Overdrive Side of the 66 into the Tri-Parallel. The Tri-Parallel has 1 Pedal in each of it’s 3 Channels. I send out of Channel 1 “send” to an EHX Soul Food and return to Channel 1 return. I send out of Channel 2 into a Xotic SL Drive and return to Channel 2 Return. I send Channel 3 out to a Tone City Sweet Cream and return into the return of Channel 3.

I then come out of the Tri-Parallel into a Fulltone Full-Drive 3 > ISP Decimator > Two-Notes Le Clean > Hotone Binary Cab Sim > Cheap Eq (I know, I know, it’s a Behringer EQ700, until I can afford the new Boss 200 Series EQ, it will do) > Radial Pro DI > FOH.

In the affects loop of the center piece (The Tube Driven Two-Notes Le Clean) I have a Hotone Binary Eko > Hotone Binary MOD > Fender Marine Layer Reverb > Tone City Tiny Spring > Back into Affects Return of the Le Clean.

Cables are 90% Mogami. I’ll replace all non-Mogami Cables soon.

I like the Tri-Parallel for obvious reasons. It’s the only thing on the market I can find that allows for parallel processing the way this unit does it. It’s just a shame that EHX Customer Support could care less.
