Harley Benton DB01-BK Electric Double Bass

To get straight to the point, the side mounted support on this is terrible! Threaded inserts weren't very tightly pressed in and I had to expoy them back in when the started pulling out. The side support itself has this weird silicone-like sleeve which stops the bolts from sliding along the straight length of support, because of this the side support is very loose and wobbly. I ended up removing this sleeve and putting some rubber between the e-clips and base of the bolts, so that they pressed up against the right angle.

The fingerboard also had a few buzy spots (even with steel strings and high action) that I had to deal (one was so deep I ended up using milliput to fill the fingerboard so I didn't have to remove so much material). I also had to file the nut slots as they are sky high.

It's also worth mentioning the string spacing at the bridge (around 24mm) is quite narrow compared to an acoustic upright (around 28mm) so keep that in mind as it could be an advantage or disadvantage for certain playing styles.

The adjustable bridge also has a lot of slop and can move up and down as the holes in the top piece are much larger than the bolts that pass through them. This can cause the bridge to drag the strings upwards when tuning.

The on board pre-amp isn't too bad. I'd reommend keeping the sub-bass knob all the way down. The built in headphone amplifier is a handy feature too.

Overall it's fine if you want to tinker and once you've done that it can be a really good instrument, but if you want something playable out of the box I suggest you steer clear of this model.
