That`s a "Volkert" Custom handmade Gypsyguitar. He`s one of the best Gypsy Guitar Luthiers worldwide. Gypsyguitars usually sound very agressive, much attack, no sustain (intentionally) and very loud. They have to be used with special silk-strings and special Gypsypicks about 3.5mm strong and rounded at the edges. That`s where that sound comes from.
I recorded this guitar with a regular AKG C2000 condenser mic (small membrane). The Upright bass was recorded with a condenser mic (big membrane) right under the bridge of the bass (stuck on the instrument).
I used alittle bit of compression for all the instruments except the drums and a multiband Compressor on the master. A little reverb on the guitars. That`s it. I tend to not overdo things. Keep the mix simple.
