A tremendous amount of work goes on to put a plane in the air and get it back on the ground safely that has zero to do with the pilot.

If Leszek has a stoner friend he should rent the space behind his couch for overseas order wood storage. "Specially seasoned" wood sets drug dog off...investigation...no drugs...carry on.

210 on its end should be very much the same footprint.

You could get a matching fetching green leprechaun outfit to go with.

I saw them when they came out here on tour. The bassist had a slightly shorter then medium scale acoustic bass guitar. It looked all wrong when he could just as easily have played a uke bass.

I never took you for a grammatarian. (autocorrect rejects grammatarian but diligaf)

Iirc nominal flat in 'clock' positions is bass 10, low mid 2, high mid 1, treble 10. Start there. Be very aware that your solo tone, aka 'bedroom tone', is nearly always 'best' with more bass and less mids. In a rock band band mix that becomes a woolly lost mess buried by guitar hero 'bedroom tone' with boosted low end that obliterates the toneful bass mids.

Personally I would be way more interested in the player's groove and sound before being concerned with the try hard relic job. It's so bad it's art in it's own right. Ugly art, but rewind to the start.

No chance of someone sending contraband from UK to Poland = not worth the effort to have a look inside?

Velcro'd to the back of the cabinet?

If it's not loud enough for you to hear yourself properly you should try raising it up before doing anything else.

The ohms limit.

This is standard for a mono amp with parallel outputs. Two 8 ohm cabs = 4 ohms. One 4 ohm cab = ohms.

For completeness, most 500w amps are mono class D, either having a single output speakon jack or a parallel pair, rated for 4 or sometimes 2.6 ohms, sometimes switchable between 4 and 2.6. Sometimes class D amps consist of an internally bridged pair of output stages and a pair of output speakons at whatever rating. A single cable is all that is needed to run one cab with full available power.

..or some other equally rare dual channel amp which escaped mention in the OP. Rewiring of the cab to full stereo could overcome the possible unlikely issue. Over to OP to clarify.

The amp gives voltage. Power depends on how much load is on it. If it was a tube amp that would be different. In this case the cab is 4 ohms according to the sticky tape note. You might trust it is still what it says it is 15 years later, or investigate further.

Most of the time it wouldn't make a blind bit of difference, but some amps would go poof. Best not to mess with the golden rule of one amp connection to one cab. You'll get all the watts you're going to get with the one cable.

I suspect the taper on your master volume is further from linear than some. 30% of the loud knob travel doesn't really tell you very much on any amp. Eg vintage Trace Elliot are about done at '4'/10. Then there's the 'audio taper' that attempts to linearize the power to loudness relationship, or let a bit more out at 2 than it really should in an attempt to get more sales from in store demos. The first 10w are the loudest. The next 90w go to making it twice as loud. If the cabinet would actually use 1000w with any efficiency you could go twice as loud again. But you can't.

If he's a scammer you've probably scared him off already. On the off chance that he isn't a scammer you need him to arrange his own courier and you need to get paid in real money into your real bank account.

Which operator? The ones on the stage can make any unholy racket they like and everyone will blame the guy at the desk when all but the vocals are cut from the FOH.

To be fair, you did ask what we would like. Seems most of us would indeed like the dots. When any reader can do it you'll find your dep pool gets deeper.

Onboard you have ready access to tweakage. This is dangerous stuff as you can readily make a hash of it. Onboard generally requires a battery.

SOP is set your intonation close enough for jazz then tweak truss rod if required before final intonation.

Director's Chair. Pop cushion on seat.

Brave. Does the now missing vintage sticky goo not severely downgrade the vintage mojo value?
