GRBass AT CUBE 800 with Cover - £900 £800 £750 Delivered in UK.

In brand new condition with original box for shipping. Purchased from Bass Direct on December 17th 2025 so just over a month old. Tried out at home and then unused. The protective film hasn't even been removed. The combo cost £1,250 and the cover was an additional £70. 

 

800W RMS (AES Standard) - 450W 8ohm RMS (AES Standard)

W40 x D35,5 x H45,5 cm

9 Kg - 19.8 lbs

Horn Driver 1" - ON/OFF and 3 positions switch

38 Hz to 18 kHz

98 dB SPL

 

My plan was to use this to take to rehearsals to allow a more consistent sound with my gigging GRBass stack. I've since seen a bass I want to buy so am selling this and a few other bits and pieces to finance it. 

 

Potential buyers are welcome to demo in Glasgow.

Highly recommended to buy from.

Recently bought an amp from John.

All his gear is absolutely immaculate, and he's a thoroughly great person to visit and have a (bass)chat with.

Price drop to £800.

Can you run a 4 ohm extension cab with this combo, or will the amp only take a second 8 ohm cab?

[JohnR]

I couldn't find specific mention of this in the manual but did find this post from 'the other place'.

I just noticed that on the photo of the back of the combo it actually states 2.7 ohms minimum load.

Nice, thanks.

Withdrawn as I've decided to keep it at this price. I found other ways to fund the bass I wanted to buy anyway.
