Constant hiss from Yamaha THR30iiw when on power adapter and using a cable connection

hi, redditians-thrians

Recently visited a private person who was selling yamaha thr30iiw + line6 relay

The seller said that a combo is almost not used and is in pristine state and combo + transmitter were bought at the same time. Also, he doesn't like playing electric guitar. An acoustic Furch was hanging on the wall. A stratocaster was on a stand.

What I faced:

  1. The wireless transmitter line6 was uncharged. Also, a receiver's jack was polished to matte
  2. Katana on stationary power was giving a constant unavoidable hiss which didn't disapper even after switching from single coils to a humbucker.

I was using the same cable as I use with other amps. The cable is from Fender and is silent with my Katana 50, yamaha thr10ii, microcube and all other devices. The guitar I used for test is completely OK (fender player strat HSS)

Hiss was present even on a clean amp models and didn't depend on anything. Switching between amp models didn't remove this hiss, as it didn't disappear between clean/crunch/hi gain amps and after any rotations of knobs.

When I was playing the same cable/guitar on my recently sold yamaha thr10ii, everything was silent or adequately hummed on hi gain amp models.

Is it a hardware issue of a specific thr30iiw or a hardware design flaw?

P.S. When I was leaving the seller's apartment, he closed the door very loudly ))) But his cat was sooo handsome.

THR30ii green light solid, battery seems charged but wont turn on?

When plugged in the green light is solidly on (suggests the amp thinks the battery is fine) but it wont turn on. Unplug and there are no lights and it wont turn on.

  • Battery voltage measures 12v
  • tried the reset (1,3,5 and power)
  • nothing appears on the display at all and device doesnt connect to phone
  • taken apart, no visually obvious failed components

any ideas where to start diagnosing?

Used THR10ii wireless vs THR30 ii

I am torn between used THR30 ii at 230usd and used THR 10ii wireless at 190usd in my city, which one is a better deal? Would like to know some first hand experience from fellow THR users.

  1. Will both be good with bass guitar since it will be my first amp in the house and my yamaha HS5 monitor speakers lack bass response so I am looking forward to finally practicing bass guitar with this amp

  2. And how is the bluetooth speakers sound from both, are there any differences?

sidenote: someone offered me katana 50 mk2 in mint condition at 90usd, but I heard the sound is not as good as Yamaha THR, would love to know if anyone have experience in that as well, thanks!

THR30IIW as pc speakers and portable bt speaker on top of being practise amp.

Hi everyone! Three quick questions:

  1. Getting this practise amp saves me from buying overwhelming amount of gear (pedal effects, amp, extra cables, pedal platform etc)?
  2. It can work also as a quality desktop PC speakers?
  3. It will also work perfectly as a portable BT speaker to play music in the garden when my friends drop by?

Do I get it right? :O

//Big thanks to You all! I've read every comment and am very gratefull for your experiences. I know what to expect now. It's bought and I'm waiting for the delivery! :D
