John East - passive/active switch

[NancyJohnson]

Just looking for a quick answer - is it possible to install and (more importantly) operate a John East Uni-Pre 3 (or 4/5) without the active/passive switch (so it's active all the time?).  Or would I just install the pre-amp and leave it in the 'on' position in the cavity?  Thinking of installing one on a bass I'd prefer not to make a hole in.

May as well leave it in the cavity and retain to option to use the bass in passive in emergency situations?

This may help someone moving forward - I spoke to John, he said there's a method of putting a jumper over the terminals that the switch uses so the bass is always active (ie no passive switching option).  He just said that if you want this at an option you need to include this in the order and he'll include this jumper in the pack.  Good to know.

 

I suppose once I convert a bass, realistically I'm never going to go passive again!

Good evening. Old topic but I need to to the same with my Uni Pre 4 knob pre amp on a bass with active pickups. Do you know which pins should be shorted?

If you want to give it a day or two, I'll pull my Hamer out and let you know.  He did one without the power switch for me.
