I’ve been using my son’s bass guitar which has active electronics and takes a 9V.
So if I leave the cable in, the circuit stays active and the battery wears out, right?
Also I once had a Goodrich volume pedal with a battery and sure enough, the battery wore out without me realizing it (had left cable plugged in).
I mean...musicians leave cables connected a lot of the times...how can this possibly be an acceptable circuit design?
Pedals on pedal boards have gone almost completely to power supplies for that reason and that’s fine. But onboard guitar circuitry and volume pedals should auto power down if inactive for a set period of time, shouldn’t they?

Would be nice, but a "power-down/standby/power-up" circuit will in itself draw some power, so the question is how much battery-time that is saved by a "power-down" circuit, and at what cost.
There are also the issues with finding right delay-time and sensitivity for "power-down" and "power-up" levels, that isn't easily affected by noise – electromagnetic and acoustic – in various environments and situations. Can end up being quite confusing what "mode" the circuit is in at any given time.
A jack-switch is more reliable. |

| If you're tempted or liable to leave the cable plugged in, the simplest solution would be change out the volume pot for one with an on/off switch, like they used to have in radios and TVs. They're cheap and easily available. The downsides are that they're about a half-inch deeper than a standard pot, so they might not fit in some thin, solid-body guitars. Also, most all of them are also linear taper, so that might affect you if you tend to use the pot (for expression) as you're playing. |

I've added a "power on/off" switch to my Goodrich MatchBro and for several others with a MatchBro. All I did was put the on/off switch in series with the ground wire that goes to the input jack on the MatchBro (the original power on point). Thus both a guitar cord plugged into the input jack AND the on/off switch "on" is required to power on the MatchBro.
They could do it (and should do it) to other devices including guitars and basses. |

From the original post: "Pedals on pedal boards have gone almost completely to power supplies for that reason....."
I really don't think that is the reason pedals on pedal boards have gone to power supplies. |
