wouldn't it be so much more convenient and reliable
to just plug a guitar into the mains power supply
and leave the battery powering the active pickups/EQ
to recharge over-night..
or a least a few hours before each gig..
.. and as much as i'm reading your replies with keen interest..
i'm not very techno-smart regarding electrics theory..
so am getting a bit confused over 9v rechargeable batteries being
truly 9v or not..
[got to admit i've never bothered with rechargeables before.. only ever bulk bought standard disposables.. but now me and the mrs are trying to be more 'eco-friendly' so i've just blown my xmas woolworths gift voucher on a bunch of rechargeable batteries]
.and.. right now in front of me, i've got a UK purchased 9v rechargeable which i would have expected to be able to use use in most active circuit guitars;
printed on this battery is..
" 9v 140mAH... Standard charge: 14mA for 14 hours / Quick charge 28 mA for 7 hours.."
so will it be fit for its intended purpose .. or not..!!??
