Spring Reverb Mkii, alu panel

New Features of the Spring Reverb Mkii include:
- Internal Feedback control with CV input, dedicated attenuverter and with invert switch for maximum feedbackiness
- Wet out and feedback in sockets for more flexible patching
- 3HP Expander – allows for instant switching between reverb brick and spring tank – or set a blend between the two
- Expander also allows for front panel send and return to spring tank.
- New improved circuit

More Features:
- Works with a variety of spring reverb tanks (not included), or with the Accutronics BTDR-2 reverb ‘brick’ designed by Brian Neunaber (not included)
- Vactrol (VTL5C3) crossfade between dry and wet (vactrol circuits are variable in their ability to go completely 100% wet, like the Make Noise Echophon for example)
- Tilt EQ on the reverb send to tune the voice of the reverb
- X-Fade input so the module can also be used as a standalone vactrol crossfader (crossfade demo)
- Feedback circuit with positive and negative phase
- Attenuverter on the crossfade CV input
- 6hp wide (NB: If using the brick, mounted horizontally, the brick extends 5mm over the PCB to the left of the module, around 25mm back from the front panel, so mount the reverb next to a shallow module)
- Expander with Front panel mount Phono sockets & Crossfade between reverb types.
