1. At the request of friends, the effect device has three distorted modes of timbre: Turbo RAT timbre, Vintage RAT timbre and Dirty RAT timbre. Switch with a button switch. Supports both power supply and power supply, 9V-12V can be used. There is a voltage regulator circuit inside.     2. The material used in this machine is classical. The first part of amplification is imported field effect transistors. K30A, tuning op-amp is LM308N of the old dismantling machine. This kind of chip has been discontinued. So there is not much on the market. The sound quality is very close to the RAT of the 1980s-1990s, commonly known as rat effect device.     3. o input and output and power outlet are set above. It can save the space of a single block.     4. Tailor-made shell, pay attention to the sound of PCB circuit board design. Thus, the effect of the effect device is guaranteed.     5. True Bypass design guarantees zero tone dyeing of direct communication signals          Type: Logic ICs     name:Distortion Effector     Condition: New     Model: RAT     colour:Black     Material:plastic          Package Contents:     1 x Distortion Effector          Only the above package content, other products are not included.     Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
