This one was sold in the late 60's by Bas v.d. Rest Muziekinstrumenten, Den Haag, The Netherlands. And now back in Den Haag again!!
Bas vd Rest was a legendary music store where the roaring Dutch music scene went to test (and buy) their instruments at full blast in the store!! Some even had a few lessons in the back of the office after the purchase for a couple of weeks.
Originally designed for bass players, many guitarists decided to try these out and noticed that they could get really interesting tones with them. The Bass model was a bit smoother than its Lead counter-part. It could easily be converted into a Lead circuits as well without altering too much to the original circuit.
The 50w Bass spec also has a hair less gain then the Lead version and will sound closer to the legendary JTM45 amp that preceded it! Even though, the 50w Bass packs quite a wallop of power!!!
50 or 100 watt?
Both will be powerful and of course loud. 100 Watt amps can be generally thought of as punchier with a tighter bass response and of course more headroom. 50 watt amps can be thought of as more of a “blended” raw sound when the amps are turned up to distort with its particular tone. It’s a subtle difference between both but sonically they are a tad different. One cannot say that an equivalent 50 watt amp will have more distortion than a 100 so don’t look for more gain to pop out of that 50 watt amp. Also, don’t think that the added two extra tubes in a 100 will cause more distortion. In truth, they are about the same but have a different feel and response.
