Hey all,
surfing around on the net at work i came across a mod that will allow the hold function to work in the short and medium setting as well.
I printed it out to read later. I did a few google searches and couldn't find it again to share with the rest of you. Basically you added a spdt center off (sp3t maybe) lifted a diode or two.
I'll type out the main section. If anyone knows the author, or source, please let me know so they can be creditted.
This only works for the DD-2 and old DD-3s, maybe others...dunno

"look on the bottom half of the switch on the scheme, the s/m/l positions go to address pins on the controller chip (the BIG 64 pin one) to determine which of the 3 settings will take effect. Theres a little table on the scheme that shows whats going on with the address pins and the modes (thanks boss!). The hold position goes somewhere in the addition, but also via diode D9 goes to the long setting's address. SO disconnect D9 anode, and hook that to a throw on the SPDT center off toggle, hook the toggle's common up to where you just diconnected D9 from. Then make a new diode go from the free throw (anode end)on the toggle to the cathode of D11 (cathode end). That should do'er. Fix 'er right up.
All this does is make it so the addresses combonations can happen when the hold mode is activated. Both address pins high, its long, one of them, its medium, and when none are high (when the toggle is in the center, and voltage goes through neither diode) its the short setting"
Thats quite a bit of typing, but sounds as easy as the hi-cut mod but with a thinner switch. He mentions adding a tiny 2p6t in place of the normal switch to make it look pro, bet it would.
I just did the regular hicut mod on my dd3 witha .047cap on the e.level pot, now the echo doesn't have the bathroom tile sound
