denyrunner Posted October 29, 2021 Share Posted October 29, 2021 Saw an ad for the Ampero Press Passive Volume / Expression Pedal. Has anyone tested this with hx stomp's expression 1/2 input? Wondering if it works well and as-well as Mission? Quote Link to comment Share on other sites More sharing options...
piepolitb Posted November 11, 2021 Share Posted November 11, 2021 Hi, I have the Hotone, very nice pedal but I can't make it work properly: I have 2 exp pedal un a Y cable (TRS --> TS + TS): the boss exp pedal works great after some tweaking on the settings. The hotone don't: it gets to 100 in toe position, 0 to middle and it sweeps back to 100 in heel position. Any ideas ? I'm living with that issue thanks to a very badly DIY workaround: a placed a cable under the heel position so that I can't go further than middle position :D Quote Link to comment Share on other sites More sharing options...

duc1000 Posted December 28, 2023 Share Posted December 28, 2023 Did you find a solution @piepolitb? I have the same issue with my Hotone Ampero Press. Thx Quote Link to comment Share on other sites More sharing options...

Thx Hi, I had the same problem with the new Hotone Ampero Press 2. The solution is to use a TRS cable (stero cable with two black rings). I tried a Y cable with 1 TRS and 2 TR to use the button but it doesn't work, the expression pedal goes 0-100 (middle)-0 The problem with this is that I can not use the foot switch.

guig53 Posted January 11, 2024 Share Posted January 11, 2024 No solution for AMPERO II PRESS with HX effects.. :( It's a shame cause it's light compared to the Mission pedal. Quote Link to comment Share on other sites More sharing options...

Why? I think it has to work with a TRS cable. In HX Stomp works Quote Link to comment Share on other sites More sharing options...
Joepeggio Posted January 12, 2024 Share Posted January 12, 2024 I found IME that the "expression" pedel in Hx/Helix is just looking for a simple resistance sweep as a volume pedal does. One side of a volume pot to ground. Anything labled "expression" doesnt not seem to work. Quote Link to comment Share on other sites More sharing options...
gnumarco Posted Thursday at 12:30 PM Share Posted Thursday at 12:30 PM Hi all. Digging out this topic as I found a solution. I have read in other forums that the Ampero Hotone II seems to work with the HX Stomp. I have a Helix Rack, and it did not work. I had the "famous problem" of values going 0% - 100% - 0%, which is not ideal. So, I plugged a TRS cable to my Hotone II and tested the resistance between "tip - sleeve" and "ring - sleeve". "Tip-sleeve" goes from 0 Ohm to 10k Ohm linearly, and "ring-sleeve" goes from 10k Ohm to 0 Ohm linearly as the pedal is pressed. My conclusions: maybe the Helix actually has TRS jacks but tip and sleeve are hardwired together "just in case". This way, when pedal is up or down the whole way, it shows a 0 Ohm resistance (because signal passes either through tip or sleeve), and when the pedal is at the middle position, resistance is at its max, which is approx 2.5k Ohm (if the pedal is really linear, in the middle position we have two resistors of approx. 5k Ohm in parallel, which gives a 2.5k Ohm total resistance). So, this might be, for me, the explanation of why the Helix works like this with the Hotone II. When a TS cable is used, the resistance between T and S goes: 0 Ohm - approx. 3k Ohm - 0 Ohm, not sure why though. SOLUTION: just take TRS jacks and wire Tip to Tip and Sleeve to Sleeve. Let the Rings unwired. It works perfectly with my Helix Rack. Quote Link to comment Share on other sites More sharing options...
