Unknown preamp tube / hifi

[radio]

Good morning

I bought a chinese hifi preamp and I want to use it as a second input for my amp.

I think I know how to do that but thats not my question:

6J1 Valve & Vacuum Tube HiFi Buffer Stereo Tube Audio Amp Amplifier Preamplifier

Can you school me what the 6J1 tube is about? Especially if there s a reason it could be not good for guitar.

Thanks for reading!

It's a Chinese pentode, similar to 6AK5/EF95. If preamp is with that tube, it is probably similar to VOX AC30 preamp section. Datasheets are in Chinese, so not of very much use.

There's no reason why it would be bad for your guitar

Thanks Rankot, you are a messenger of good news

That would eventually, best case, sound a bit like an Blackstar artisan,

not that I don't like Vox
