Review: Great product - Works perfectly for my drum machine
Review: Works with Pageflip page turner - My Pageflip fell about 2’ off my amplifier when packing up. The right pedal quit working. I could hear no click when holding the pedal next to my ear. The reed switch was broken. $75 for bench fee then labor and parts…too much. I bought this foot pedal and plugged it into the back of the Pageflip. Works great. You have to buy a 1/4” female to 1/8” male adapter. Total cost $20. Better than buying a new Pageflip or getting it repaired. Switch must be turned to momentary position…..away from the cord coming out the back.

## Questions & Answers

**Q: Is this a damper depal ?**
A: Yes.

**Q: Will this work as an on/off toggle for the alesis drum machines?**
A: It’s a momentary contact switch so it depends on the drum machine. I suspect it will work, but can’t be certain.

**Q: Where does it plug in? Will i work with Alesis Melody 61??**
A: Hi, Alesis support here! Melody 61 does not feature a sustain pedal input. For this reason, ASP-1 is not compatible with the Melody 61. This product is designed to operate with any keyboard which features a 1/4" sustain pedal input. For further support, please feel free to contact us directly - amzsupport@alesis.com

### ⭐⭐⭐⭐⭐ Great product
*by R***R on April 12, 2026*

Works perfectly for my drum machine

### ⭐⭐⭐⭐⭐ Works with Pageflip page turner
*by M***H on June 30, 2023*

My Pageflip fell about 2’ off my amplifier when packing up. The right pedal quit working. I could hear no click when holding the pedal next to my ear. The reed switch was broken. $75 for bench fee then labor and parts…too much. I bought this foot pedal and plugged it into the back of the Pageflip. Works great. You have to buy a 1/4” female to 1/8” male adapter. Total cost $20. Better than buying a new Pageflip or getting it repaired. Switch must be turned to momentary position…..away from the cord coming out the back.

### ⭐⭐⭐⭐ Broke after 1 month, but got a refund
*by J***T on January 10, 2024*

The pedal housing is solid, but the internal switch mechanism was brittle and only lasted 1 month before the pedal became unresponsive (in the middle of a public performance...). I opened it up to see what went wrong and I found that the wire that moves when you press the pedal had snapped as the pictures show. Alesis gave me instructions to request a warrantied refund through Amazon and that process was very easy, so I will give a positive rating because they helped me resolve this situation right away.
