This is the JAM Pedals Rattler Ltd. It features the highly valuable NOS LM308AH op-amp. A toggle switch allows you to switch between high and low gain, providing distinct distortion characteristics. This is a special limited edition Rattler from the custom shop, featuring Point-to-Point wiring and housed in a luxurious leather enclosure. I'm a big fan of RAT-style pedals, and I've bought and compared several RAT-type effects, searching for the one that best suits my setup. This one also has a fantastic sound, but I'm too frugal to put it on my board and stomp on it, so it's not for me... so I'm putting it up for sale. Thank you.
