HOTONEMulti-function 4 in 1 Switchable Volume & Expression Pedal with Buffer switch and Visible Tuner SP-30T(Included 1 PCS Additional 15 CM TS Cable By VOLKTONE)

This pedal is ingenious. You can use the switch to alternate between using it as a volume pedal and an expression pedal and tune with the toe all the way up. The sweep isn't going to be as good as a full size volume/expression pedal, but it's totally workable given the size and flexibility. The volume function and buffer sound great. It's really easy to setup with physical switches to change between display modes. The tuner works really well. Build quality is solid with aluminum rather than plastic. If you don't abuse it, it should last a long time. I am using this on a Nano board with a Nano Cortex and it's a little long for the board size, but it's still totally workable and perfect for a nice compact setup. Excellent value and functionality all-around.

This expression pedal is just perfect! It's surprisingly sturdy, stable and reliable. I use mine with a Disaster Area Designs MIDI controller unit to control the volume block in my HX Stomp or whatever other EXP duty it needs to serve. It's compact enough to fit into my board but the size and the grippy upper surface feel great under my foot (size 12 shoes). Again, what surprices me most is how sturdy it feels compared to other units in its price range...Like not worries at all while constantly using it to adjust and swell, etc.

This pedal has good voicing, I prefer the classic sound to the warm setting, which is too bass-y for me. The pedal is very well constructed, the body is metal and it should be very durable. It is smaller than most volume pedals so it should fit well on most pedalboards. One limitation: the wah output is not adjustable, it is output at the full volume of the pedal. This is not a problem for leads, but you will need to roll off the guitar volume to use the wah for rhythm playing.

Very sturdy and high quality made. Works perfect!

I originally purchased this pedal back in January, and I used it one time. The pedal is great and does what it says. So in May, I decided to use the pedal again, and the device was dead. New battery or the Power Supply would not wake up the pedal. It was past the return date for Amazon, but I reached out to the seller with my issues. The seller sent me a new pedal to replace the bad one. I really did not expect that kind of customer service, but the seller went above and beyond what I had expected. Customer Service is really what you want when you buy something, and this seller delivered.

The build quality is good and the price is great but the setup can take some figuring out. In some of my pedals it seems like it was reversed so 0 was all the way up and 100 was all the way down making configuration difficult in some places. It also needs trs cables to work.

This pedal is fantastic. The strobe tuning is incredibly accurate, the volume pedal has an excellent sweep and weight, the buffer sounds good enough to me, and the build seems very durable. Great interface, good usability, perfect small enclosure, and great value. Highly recommend this pedal!One con: the pedal’s click to go from volume to expression makes a slight noise that reaches my signal. For me it isn’t an issue, but thought I would note it.

First and foremost, this pedal works really well! Solid build, excellent quality, 5 Stars!TLDR: This pedal REQUIRES a TRS CABLE to function properly. The INCLUDED cable (TS cable) DOES NOT allow for full functionality of the pedal, so you'll have to get your own TRS cable to use this pedal!FULL STORY:It took me a LONG time to figure out how to get it to work properly.I thought the pedal was broken, since it was acting strange and did not function properly. I requested a replacement pedal to be sent out to me. The replacement pedal I received did not function properly either, just like the first one. Once I bought a TRS cable and used the new TRS cable instead of the included TS cable, it finally worked!
