Key features and benefits Adjustable reverb depth option: If you want to adjust the reverb depth, you can remove R27 and connect a potentiometer to the S G G pad. A potentiometer in the range of 20k to 50k can be used to adjust the reverb response according to your preference. This allows you to control the strength or subtlety of the reverberation in your signal. Reverb plate only: This unit provides the reverb effect without a preamplifier function, which simplifies integration into existing signal chains when a separate preamp is already in use. Separate PT2399 reverb board: The PT2399 board is a dedicated reverberation module without a microphone preamplifier. This design enables you to pair the reverb with your own preamp or audio interface as required. Wide operating voltage: It works with DC power supplies in the 6 to 15 V range, providing flexibility for different setups and power supplies. What it is and how it helps Function: A compact reverb module based on a PT2399 reverb core that adds space and ambiance to audio signals without builtin preamplification. Compatibility: Suitable for use with devices that supply 6–15 V DC power and that can incorporate an external preamp if microphone or linelevel gain is needed. Practical design: The ability to remove R27 and install a 20k–50k potentiometer offers an adjustable reverb depth option without changing the core module. Performance focus: Delivers reverb effects via a dedicated reverb board, allowing clean signal routing and easier in DIY or modular setups. 23 practical use scenarios Guitar pedal chain: Integrate this reverb plate into a guitar rig by powering it from a suitable DC power source and using your own preamp before or after the module. With the adjustable depth option, you can set a subtle wash or a deeper plate reverb to suit different songs or genres. Studio or home setup with synths and drum machines: Add a reverb tail to keyboard or drummachine outputs by connecting the module in your effects loop or direct path, using an external preamp as . The broad voltage range helps accommodate various compact audio setups. DIY electronics project: For hobbyists building a custom effects unit, this module offers a simple reverb core with a clear way to adjust the depth. The 6–15 V operation supports common DIY power supplies, and the separate reverb board simplifies testing and integration with other projects. Notes This description reflects the original product specifications: R27 reverb depth resistor and the option to use a 20k–50k potentiometer connected to the S G G pads for adjustable depth. The unit is a Reverb Plate without a preamplifier, and the PT2399 board is a separate reverberation board without microphone preamplifier. Power supply: DC 6–15 V.
