You pay VAT on the sum of the bass and the value of the shipping. You pay a flat fee for customs clearance.
The 25% is for an average bass coming from an average EU place. An expensive bass from Calais will cost same as a cheaper bass from Estonia by the time you get it.
Hang in there. I furnished most off my pedals out of the US. The first few sales were problematic to convince sellers of the ease of filling in a simple customs form and posting off like normal. Once the ball was rolling I had no problems pointing to previous easy dealings.
New suffers from shipping from further away and customs clearance charges. The likes of Thomman have got their customs clearance down to the actual cost of someone ticking a box, and super deals on shipment. Being new there's only one lot of VAT. They are making sales.
All that goes out the window on used stuff brought in privately.
If you ever had a hankering to plug in a piezo Ubass you might like to be sure the 'regular' impedance is 1M or more. Older Ashdowns don't do sfa with mine.
With 4 ohm worth of cabbage my 250 SMX doesn't get above 2' on the output or it's drowning out the drum set. I imagine this one has hardly broken a sweat its entire life.
I wonder if they had to spend vast amounts of time on site deliberating on the tonal qualities of the 50 Becquerel piano vs the 30 next door before they chose one.
Earplugs help me hear myself on bass. Maybe that works with a sax in your gob?
If there's a mic stand in front of you it might be possible to do like the big band players with a perspex reflector to bounce bell sound back to you.
I once had a drunk chick, slim with requisite bumps, squat in front of me and put one leg back between mine so she could weasel up behind my bass while I am playing and 'dance' there. Talk about distracting!!!!
