The chorus and echo are tied together, both being on when the switch was set to normal. Either chorus or echo can be disabled, but not both at the same time. The output was then processed by an integrated amp simulator to the headphone jack and low level output jack.

advertised to have a "brighter" sound. The amplifier distortion is toggled using the "cln/dist" button. The character of the distortion can be changed with the "semi/hvy" button. Semi-distortion behaves much like the "edge" setting is described to, in the
Rockman and X100 product. The Bass Ace has the most spartan controls, including mid and treble boost buttons.

XP100 and XP100a, 12-inch speakers were installed, in a 2x12 single-cabinet configuration. This product was called the XP212. A head version was also produced, called the
Rockman Superhead. It is basically a XP100, without the speakers. Due to the small production numbers, the XPRa, XP100a, XP212 and Superhead are extremely difficult to find in the aftermarket.

The last SR&D brochure featured a
Rockman Stereo Chorus pedal in the same style as the AGP and the Ultimatum. The only controls on the unit were rate and depth. Like many SR&D products it is likely that this existed only as a prototype awaiting a market-driven response. It is unknown if this

The
Rockman Stereo Echo is an analog delay. It can be used to provide "slap back" echo when no feedback is used. Increasing the delay time and adding feedback provides standard echo effects. It has stereo inputs, or a mono input if only the left input is used. One possible lineup is to put the Stereo

A new series of
Rockman products was introduced in 1984, which included the X100, Soloist and Bass Rockman headphone amps. These continued to be produced until 1994 when a 10th anniversary X100 was released to commemorate the event. The X100 is very similar to the original Rockman in its feature set,

The
Rockman brand was introduced with SR&D's eponymous battery powered headphone amplifier claiming to replace $ 10,000 of studio gear. The first generation Rockman combined multiple effects with high quality components and construction in a hip-worn enclosure using a built-in attached belt clip.

The Rockman Soloist was positioned as a lower cost Rockman product. It does not have the "Clean 2" voice. It also has different choices for effects, including a setting for chorus and a "stereo" setting that has a fixed 25-millisecond delay. It can be set to "Mono" output, removing all the effects.
593:
The control devices include the Midi Octopus and Dual Remote Loop. The Midi Octopus is used for controlling other effects. It could be used with a Midi pedal board, or be controlled by a Midi sequencer. The Dual Remote Loop is used to interface effects and amplifiers that can't controlled by other

Featuring a built-in compressor, the Rockman offered two clean modes that utilized different equalization settings with "hi power sustain": "CLN 1" can be used for R&B and country, while "CLN 2" is recommended for a wider range of use, including acoustic guitar, vocals and keyboards (electric

The A12-50 combo was released in 1993. It is a two-channel (distortion and clean) 1x12 50-watt mono combo. It lacks the chorus and reverb of the other Rockman products, but provides an effects loop for using external effects. It is probably the most conventional of the Rockman guitar amplifiers.

1991 brought a number of XP series products, that were all produced in small numbers. A low-noise update to the XPR was released, called the XPRa. Similarly, the XP100a combo was released as a low-noise version of the XP100. Another combo was released in 1991. Instead of 6-inch speakers like the

The XP series started in 1989 as a rack-mounted programmable preamplifier called the XPR that was intended for direct connection to a full-range PA system. There is a three-band EQ that allows pre-distortion changes to the EQ. The clean signal can also be mixed with the distorted signal. The

Production of the Rockman Ultralight began in 1983. It was a lower priced alternative to the Rockman IIB which replaced the original Rockman. It was very similar to the original Rockman but lacks the echo setting. Uniquely, the chorus can be disabled, allowing a dry output from the amplifier
518:
The Ace family is a much simpler Rockman design that does not have effects and uses a single 9-volt battery or power supply. The Guitar and Bass Ace were first released in 1990 and the Metal Ace was released in 1994. The Guitar Ace and Metal Ace have identical controls, but the Metal Ace is

Released in 1982, the original Rockman (Model I) advertised "custom EQ, heavy sustain, clean/distortion control, 'chamber echo', stereo chorus" and "folding headphones". The Rockman requires eight AA batteries or a "Rockadaptor" power supply adapter which mounts in the battery compartment.
549:
Generator is a related product that was released in 1987. The Distortion Generator includes compression, distortion and cabinet simulation circuitry. Compared to the Sustainor, the Distortion Generator lacks the noise gate and external loop, but includes a three-band pre-distortion EQ.
565:. The chorus effect can be mono or stereo. The Chorus/Delay is used for doubling, slap-back and reverb-like short echoes. Combining the Stereo Chorus/Delay with a Sustainor provides a complete system for recording guitar. 1987 brought the Instrument EQ, Stereo Echo and Stereo Chorus.

The release of the XPR in 1989 was complemented by the release of the related XP100. The XP100 is a complete amplifier that packages the XPR pre-amplifier with a 2x50-watt stereo amplifier and 6-inch speakers. The speakers are in a dual enclosure that can be separated.

638:
The Studio Series consists of two 19-inch rack-mount systems that were both briefly built in 1991. This includes the Pro Bass Rockman and PGE-2 two-channel programmable equalizer. Only around 20 of the Pro Bass Rockman were made. Just ninety-nine PGE-2's were made.
647:
The Pro Bass includes compression and a 9-band graphic equalizer. A foot-switchable 3-band equalizer can also be used to change the EQ during a performance. It has an onboard stereo chorus, overdrive, tape input, tuner output and headphone output.
356:
The Power Soak was re-issued one last time in 1992 as a Power Soak model III, lacking the solid-state switch, though the Power Soak III can be used both with solid-state and tube amps. The 1/4" jacks were also moved to the back of the unit.
