Bass Amp & Cab Models
Rock Classic
For 30 years now, we’ve heard the tone and felt the power of the mighty
Ampeg® SVT® that GearBox’s Rock Classic model is based on*. This
workhorse has appeared on innumerable recordings and arena stages
worldwide – there is no equal to the original SVT® and its 300 watts of
pure tube magic. First introduced in July 1969, the SVT® set the tone,
punch and arena-rattling standard for all future big gun bass rigs. Its users
have included everyone from The Rolling Stones to Van Halen, and pretty
much every “rock” bass player in between. For GearBox’s Rock Classic
Model, we selected a 1974 Ampeg® SVT®, and we’ve also given you a
70’s SVT 8x10 speaker cabinet to pair it with. The sonic combination of
this head and cab is beyond big, but you had to pray that your bandmates
would help you move it! Thanks to GearBox, you can now get big classic rock bass tone without
frequent visits to the chiropractor.

Flip Top
The Flip Top model is based on* a 60’s Ampeg® B-15 Portaflex® — one
of the most popular studio bass amps of all time. It’s tuned and front-
ported, has a closed back, is 25 watts with a single 15-inch speaker, and set
a new standard for cabinet and speaker efficiency, tone and convenience
in bass amplification. If we had to sum up the amp’s sound up in one
sentence, we would simply say: Listen to James Jamerson’s bass playing
on the Motown®/Tamala records of the 1960’s — The Supremes, The
Four Tops, The Temptations, Marvin Gaye, Stevie Wonder, and many
more. Jamerson played bass on more Motown hits than anyone else, and
his choice for amplification was the Ampeg® B-15. We think you’ll agree
that the sound of his P Bass® through that amp on those records is as fresh
and exciting today as it was 35 years ago. And if he’s not enough to convince you, how about “Duck”
Dunn! Don’t get us started....
