EU  Price does not include EU VAT

Choose panel type/colour



The Music Thing Spring Reverb Expander is designed to connect to the Music Thing Modular Spring Reverb Mkii. The expander adds the ability to blend the reverb tank and brick outputs and manually crossfade between the two. This module also adds the option to connect to your reverb tank from the front panel rather than the back PCB of the main Spring Reverb module. This expander is passive so doesn’t require a power cable.

Note: This expander is only compatible with the MTM Spring Reverb Mkii – It will not work with older revisions.

Build Document:


  • Front panel Send & Return sockets to Reverb Tank
  • Set blend level between Spring Tank and Brick Outputs
  • 3HP Front Panel – In Silver or Black Aluminium
