Overview
The 2019 version of the
Aquaboy Deluxe
is a complete re-design of the 2015 project. This version
incorporates many of the requested features lacking in the previous version: 15v operation, on-
board charge pump, and both true bypass and tails footswitches. It keeps the same 1590BB
footprint, although a 125BB is also a good choice. The ABDX has about 550ms of delay and includes
modulation (triangle and squarewave).
This is complex project that should not be under-taken by novice builders. It is also a costly project
to make. The BBD chips, clock and compander alone will set you back $50 or so. However, this is
the type of project where money spent will go a long way toward making a unique and professional
sounding delay AND still be cheaper than many commercially available analog delays with similar
features.
NOTE:
smallbear is currently out of the Xvive MN3005 re-makes. So, if you do not already have these
you may be waiting a while to get them. I do not have any sources for the NOS MN3005 and most
likely neither does anyone else. Hopefully, smallbear will be able to get more of the re-makes soon.
You will need a multimeter, audio probe and some kind of testing rig/breadboard set-up to get the
ABDX properly set-up.
Controls
• DELAY:
The total amount of signal delay from slapback to approximately 500ms.
• FDBK:
The number and intensity of delay repeats from one to infinity/self oscillation.
• MIX:
The level of delay signal relative to the dry path of the guitar signal.
• RATE:
The speed of the delay modulation from slowest to very fast.
• DEPTH:
The intensity of modulation from moderate to extreme.
• MOD:
This On/Off/On DPDT allows you to choose between square, none and triangle modulation.
Trimmers
• T1:
Sets the maximum amount of feedback possible in order to control the total range of the FDBK
control.
• BIAS1, BIAS2:
Used to set the biasing point on the input of each BBD.
• CANCEL:
Sets the mix of the two outputs on BBD2.
• CLOCK:
Sets the lower limit of the clock frequency used to drive the BBD chips.
Terms of Use:
You are free to use purchased

circuit boards for both DIY and small commercial operations. You may not
offer

PCBs for resale or as part of a “kit” in a commercial fashion. Peer to peer re-sale is fine, though.
Technical assistance
