A friend of mine suggested that I leave the cord plugged into the guitar. Removing and inserting the cord daily for practice may damage it and reduce its life. Is it okay that I leave my guitar connected to the amp always and just switch off the amp supply, and turn it back on the next day for practice?

This should not be a problem, although there is no harm in unplugging the instrument. The instrument jacks and the cord are very durable. One danger with leaving it plugged in while you are not holding the guitar is that you might trip over the cord, which could pull on the guitar and knock the guitar off its stand, which might damage the guitar.

Furthermore, players sometimes, while standing up and playing the guitar, accidentally step on the cord and yank it out of the jack on the guitar. That could lead to damaging the cord (and it will make a very unpleasant loud sound through the amplifier).

Here is a YouTube video that shows the correct way to connect the cord to the guitar by looping it through the guitar strap to relieve the tension upon it.

    Yeah, tripping over was the main reason why I used to unplug it everyday. Thanks, so I guess I will continue to do the same

  • I have broken the headstock of a guitar by stepping on a plugged-in cable and the pulling force tipped the guitar over and the impact cracked the headstock. +1 for pointing out that danger. Oct 20, 2015 at 19:44
  • Hollow-body electric guitars like the one in the video are also prone to having the wood around the output jack ripped apart when the cable is kicked. That is less traumatic than a broken headstock, but I am sure it is expensive to repair.

While the quarter inch plug is known to be durable so that frequent unplugging should be ok, it is noteworthy that the pickup's preamp might be switched on and off by the plug. This integrated amp typically runs of a 9-volt battery (or sometimes two of them). Leaving it turned on by not unplugging the cord will therefore result in a faster discharge of the battery and a more frequent need to change it.

Note however that not all electric guitars are active, so check first before troubling yourself.

    Correct, however most electric guitars do not have any preamp built in. The main reason is irrational “vintage” buzz, but this is actually a worthwhile point in favour of passive electronics: I have more than once forgotten to unplug my active bass, and ended up with an empty battery just when I needed it. (Normally, I power the active circuitry with a custom phantom power system, which eliminates the need for batteries entirely.) Oct 20, 2015 at 20:46
  • @leftaroundabout, right, but then again it is quite easy to check whether it has one or not ;)

  • but many beginner guitarists probably never thought about it, and it wouldn't seem far-fetched to think that every electric guitar must have a battery. I wouldn't want them to now start unplugging their instrument in every little pause, to avoid failure of a battery that doesn't in fact exist at all... Oct 20, 2015 at 20:56
  • @leftaroundabout, sure but I guess no one is going to unplug for a cigarette break.

  • It is an important distinction and the rules apply differently depending on if you have a battery operated pre-amp in your guitar (as on many acoustics) or if you have passive pick up system (typical of most electric guitars). Active battery powered pre-amp - unplug after playing to avoid depleting battery. Passive pickup with no battery - okay to leave plugged in all the time to avoid wear on socket. Oct 21, 2015 at 3:40

1) It does no harm to the connector in the guitar, or amp, or the connectors on the cord, to leave them plugged in.

2) If leaving the cord connected bends the cord tightly, curving it with a small radius, the cord itself or the cord-to-connector joint may be damaged. The vast majority of cord failures happen within 300mm/12inches of the end, usually right where the connector body or connector strain-relief ends. When a cord fails, cutting off that last foot or 300mm and re-attaching the connector will often revive it. Unless its been over-bent somewhere other than the ends, or stretched along a large area.

3) If you have battery operated effects boxes, a preamp in the guitar or anything else involving a battery, leaving cords plugged in to that item may leave it switched on, so you'd want to disconnect the cord and save the battery when not using the equipment.

4) Tripping over a connected cord and pulling over the instrument, amp, or both, is a constant danger. On stage or in a practice space, I might leave it connected. If there's foot traffic, disconnect. Be safe, not sorry.

  • I bought an active bass, and didn't really understand the relevance of having a battery for the pre-amp. It died out after four months. It has died during practice so I make sure I carry extra battery at all times and put a new one in my bass the day before a gig! GOD Bless you. Aug 26, 2017 at 1:37
