Squier Strat Guitar: Hoe kan ik resonantie/hoge toon verhelpen?

Sat, 04 May 2024 01:17:09 -0700

Als de gitaar wordt aangesloten op de versterker veroorzaakt deze een hoge (piep)toon. Dit valt iets te verminderen met het draaien aan "toon" knop maar verdwijnt niet helemaal. Wat kan hiervan de oorzaak zijn en hoe zou dit te verhelpen zijn? Alvast dank voor de reactie. Met groet Francois

Roland G-800: Aanslaggevoeligheid toetsen werkt niet helemaal goed

Sat, 03 Oct 2020 14:26:40 -0700

Ik heb problemen met de aanslaggevoeligheid van een aantal toetsen. Soms werkt er één wel goed maar ook vaak niet. Het is dan net of je hem keihard inslaat want hij klinkt erg hard.

Wat zou ik hier (nog) aan kunnen doen? Ik wil hem nog steeds niet kwijt namelijk.

teenage engineering EP–133 K.O. II: Need to replace the Fader and an encoder knob, need parts?

Fri, 01 May 2026 17:14:56 -0700

I bought one of these used, and the fader and the BPM encoder knob do not function correctly. I'd just replace both myself, but not sure what replacement parts to order. I've seen some sources say I just need a 45mm Type B 10k for the fader. I'm not sure about the encoder. Looking for answers.

teenage engineering EP–133 K.O. II: Input is not detected

Fri, 17 Apr 2026 04:12:14 -0700

Hi !

When I plug a 3.5mm jack cable in sample mode nothing happens.

The displays stays in MIC instead of switching to LR. I assume this is a hardware problem but I'm not sure about it. Is there any way to fix the stereo jack 3.5mm input ?

Thank's

Alain

Epiphone SG Guitar: How do I prevent my guitar's input jack from loosening?

Fri, 10 Apr 2026 03:47:33 -0700

The input jack on my Epiphone SG electric guitar keeps loosening after several hours of (nonconsecutive) play. I don't want to strip the backing plate screws by removing the plate to tighten the jack once a week! The jack on this model is on the front face of the guitar.

Other than looping the cable through the guitar's strap to prevent excess pressure on the jack, what's a good solution to this problem?

Possible ideas I've thought of include loc-tite (which I'd rather avoid) and replacing the jack's washers with larger diameter ones to prevent the tension from compressing the wood.

Teenage Engineering OP-1: Why won't audio come from the right channel of my OP-1?

Tue, 17 Mar 2026 18:42:12 -0700

I have made sure that all the tracks are panned towards the center, but no audio comes from the right channel. If it is plugged into speakers or headphones and panned to the center, audio only comes from the left side. If it is panned to the right no audio come out. I was curious as to if there is something I am missing or if this is a hardware problem that requires repairs/parts. Thanks!

Electronic Keyboard: Casio WK3700 DSP not working

Wed, 04 Mar 2026 00:55:41 -0700

I have an old Casio WK3700 electronic piano/keyboard.

When powered on in Grand Piano mode 000 it works fine. If I try any other mode the DSP button lights up and it emits a distorted thrumming sound and eventually powers off.

I assume the DSP circuitry is stuffed. Video
