Overview
The Promenade is an envelope filter based on the EHX® Bass Balls™. I’ve included some of the
mods suggested by Mark Hammer on the DIYSB forum. These mods give the builder more control
over how the envelope behaves as well as the bass and treble frequency response.
This should be an easy project for most builders. There’s nothing tricky, nothing to be tweaked to
taste or in need of further modification, IMO. It sounds great on bass, baritone and guitar.
Controls
• BASS, TREB - Sets the frequency range of the swept filter for the low and high end.
• SENSE - The sensitivity of the envelope filter. This controls how much signal is used to trigger
the envelope. There will be a couple of “sweet spots” depending on the instrument used (passive/
active bass, etc).
• ATTACK, DECAY - These controls determine the overall shape of the envelope note. Turning
them up will increase the attack of the envelope and make the decay of the envelope much
longer. Attack, Decay and Sense all work together to offer a wide range of envelope control.
• CLEAN/DIST - Left position is clean signal out. Right position adds two silicon diodes to ground
for some hard clipped distortion.

offer Promenade PCBs for resale or as part of a “kit” in a commercial fashion. Peer to peer re-sale is fine, though.
Technical assistance
for your build(s) is available via the madbeanpedals forum . Please go there rather than emailing me for
assistance on builds . This is because (1) I’m not always available to respond via email in a timely and continuous manner, and (2)
posting technical problems and solutions in the forum creates a record from which other members may benefit.
