The '''Ampeg PR-1832HE''' is a bass cabinet, made by US bass amplifier manufacturer, [[Ampeg]] in the 1990s. The PR-1832HE is the larger brother to the PR-1532HE. Both amps feature a 4x10/2x10 speaker designs that are slightly slanted and sit on top of an 18" subwoofer. The cabinets are designed for high-SPL and low distortion. These cabinets were inspired by and co-designed with the well-known US bassist Victor Wooten, originally designed for Steve Bailey, who was Vooten's touring keyboardist and bassist.
The '''Marshall DBS 7400''' (Dynamic Bass System 7400), is a discontinued 400W RMS bass guitar amplifier head. The heads were being produced for about five years in the 90s before being discontinued and were made in both standard/boxed and rack versions. The amps are capable of driving loads down to 2 ohms, which means any possible combination of bass cabs could be attached to them. According to DBS 7400 users, the amps were also really heavy (which is probably one of the reasons why Chris threw them out of his live rig).


The PR-1832HE specifically features a single, 1x18", 400-Watt, flat sub speaker, two 10", 150-Watt, low frequency speakers, two 6,5", 75-Watt closed-back mid-frequency speakers, and a bullet horn tweeter. The cabinet is bi-ampable between the 18" sub and the 2-10" low frequency components. It also features casters and a rear bar handle aswell as self-retracting side handles, making it easier to move. All-together, the PR-1832HE produces 600 watts of power. The cabinet weighs about 170 pounds.
Chris used two of these amps live ever since Showbiz all the way through to the end of The Resistance tour, where he ended up using four. In 2012, he switched to [[Markbass]] and [[Kemper Profling Amplifier|Kemper]] ampliers for his live rig. Marshalls have also been used by Chris in the studio since Showbiz, with the exception of [[Simulation Theory (album)|Simulation Theory]]. In the studio, the DBS 7400's are used as two distortion amps (one for Big Muff and another for Animato) and an Ampeg SVT-VR is handling the clean signal. The sound of the amplifiers is regarded as one of Chris's staple sounds.


Chris used the cabinet in conjunction with the [[Ampeg SVT-II Pro]] head during the Showbiz tours in 1999, and (probably) in the studio aswell. Upon improoving his setup for the Origin of Symmetry era and the addition of the [[Marshall DBS 7400]] heads, the cabinet was replaced with several other [[Marshall]] cabinets; the [[Marshall 7215 Bass Cab|Marshall 7215 2x15 cabinet]], the [[Marshall 7115 Bass Cab|Marshall 7115 1x15 cabinet]] and the [[Marshall 7410 Bass Cab|Marshall 7410 4x10 cabinet]].
Wolstenholme usually pairs the amplifiers with [[Marshall 7410 Bass Cab|Marshall 7410]] 4x10, [[Marshall 7215 Bass Cab|Marshall 7215]] 2x15 and [[Marshall 7115 Bass Cab|Marshall 7115]] 1x15 bass cabs.
 
In the studio, he usually runs two of them at once, providing signals for his two distinct distortion signals. They run in parallel with the [[Ampeg SVT-VR]], which usually provides the clean end. This setup, however, varies from time to time, depending on the song.

Marshall DBS 7400
Two DBS 7400s in Chris's OoS setup

The Marshall DBS 7400 (Dynamic Bass System 7400), is a discontinued 400W RMS bass guitar amplifier head. The heads were being produced for about five years in the 90s before being discontinued and were made in both standard/boxed and rack versions. The amps are capable of driving loads down to 2 ohms, which means any possible combination of bass cabs could be attached to them. According to DBS 7400 users, the amps were also really heavy (which is probably one of the reasons why Chris threw them out of his live rig).

Chris used two of these amps live ever since Showbiz all the way through to the end of The Resistance tour, where he ended up using four. In 2012, he switched to Markbass and Kemper ampliers for his live rig. Marshalls have also been used by Chris in the studio since Showbiz, with the exception of Simulation Theory. In the studio, the DBS 7400's are used as two distortion amps (one for Big Muff and another for Animato) and an Ampeg SVT-VR is handling the clean signal. The sound of the amplifiers is regarded as one of Chris's staple sounds.

Wolstenholme usually pairs the amplifiers with Marshall 7410 4x10, Marshall 7215 2x15 and Marshall 7115 1x15 bass cabs.

In the studio, he usually runs two of them at once, providing signals for his two distinct distortion signals. They run in parallel with the Ampeg SVT-VR, which usually provides the clean end. This setup, however, varies from time to time, depending on the song.
