Vintage GK 400RB bass head dated to 1998 by GK sales rep. An incredibly powerful and versatile solid state head. Personally, I've always preferred solid state to tube for bass — gets crunch/punchy/etc. at a way quieter volume.

Comes with:

• A soft traveling case
• Grounded power cable
• 1/4" speaker cable

The hard interior of the case has one little hairline crack that's been there since I bought this amp (~2016) and it hasn't gotten any worse through hundreds of shows.

The high-mid knob is also missing the level indicator sticker, but you can still dial it in if you just start at zero.

Trying to get the serial number dated via GK...stay tuned.

$300

Impedance: 4 ohms or 8 ohms
Output: 400 watts
Etc: Direct out; effects loop; two ¼” speaker outs
