Behringer B-TRON III Auto Wah Envelope FilterThe B TRON III is a vintage envelope filter that creates a Wah or vowel sound when you play a note. It includes three filter types via the Mode switch that includes low , band , or high pass settings for a nice quack or a nice high frequency sizzle. It works great for bringing the funk with either guitar, bass or keyboards. The Range switch on the B TRON III can be toggled between low, so you can get more vowel like sounds, or high to emphasise more

Very comfortable and robust. This definitely looks and feels like a premium item. I had bought a few alternatives that were cheaper and they fell apart quickly. This one seems to have pretty resilient stitching and the fabric doesn’t bunch up which could cause a tear. The base has a non slip texture so it’s not going anywhere without some force. The cooling feel is a nice touch too.

Extremely Comfortable Wrist Rest

Size: Compact, Pattern Name: Keyboard, Size: Compact, Pattern Name: Keyboard

Hands down the best keyboard wrist rest! Fits perfectly with my HyperX Origins keyboard, almost like these products were made for each other! I really like the minimalist design of it and the quality does not suffer because of this. The memory foam is more comfortable than the memory foam on my bed, and the cooling gel stays cool no matter how long I'm using it. I have mine on a desk mat and it doesn't slip at all, it stays exactly where I need it which is great! Whether you're someone uses a computer for work all day or just a casual gamer, I highly recommend getting this wrist rest. It will change your life!

The best wrist rest I've used.

Size: Compact, Pattern Name: Keyboard

It has just the right balance of firmness and softness. The cooling gel does keep it cool. It is durable. Its rubber grip holds it firmly on my desktop. If I need another one, I will purchase this product.
