Modular Speaker Amp Preamp Guitar Setup

Going Modular: Separate Pre-Amp, Amp, Speaker Cab

Introduction

Back in the mid 1990s, When I bought my first electric guitar, I spent time researching and thinking about which electric guitar I’d get, and I didn’t pay much attention to which amplifier I should purchase. At the last minute, I chose a 1×10” used Rickenbacker combo amp from the musical instruments store. When I got home, I plugged the guitar into the amp which had no reverb, and no overdrive or distortion channel. It did have vibrato, though. After a few months of playing through this amp, I purchased a Zoom digital multi-effects pedal board and spent the next couple of months learning how to use it while dialing in tones for chorus, phasor, flanger, distortion, auto-wah, and reverb.

With my amp and mult-effects pedal eventually dialed in, I was all set to bring them to my first garage jam session. When I arrived, I noticed the two other guitar players had a 2×12” combo amp and a 4×12” half stack with a head unit. It was the mid 1990s, and half stacks with head units were very popular, and also extremely loud, large, and heavy to carry around. Very quickly, I learned that my 1×10” combo amp could not compete with the power and volume of the 2×12” combo and 4×12” half stack. I went home that day and did some searching for a used half stack and found a Carvin 100 watt, all tube head unit with a 4×12” half stack. This Carvin amp was super loud and had lots of clean headroom. I brought it to my first gig, and then my second and third, and after a few more it became clear that a 2×12” combo amp with wheels would be easier to carry around.

I sold the Carvin half stack and bought a Crate 2×12” 100 watt hybrid amp, it had a couple of pre-amp tubes with a solid state power amp section. I only used the clean channel on the amp and purchased a bunch of analog pedals to replace the digital multi-effects pedal board. This setup would last me for years, and with an EQ pedal, I was able to shape the tone quite nicely.

Fast forward to 2019, and it’s time for a new guitar amp. But this time, I’m going modular with a separate pre-amp, separate power amp, and separate speaker cabinet. The sound of a Fender Twin Reverb amp became a point of reference, as I had played through them at rehearsal spaces, and have some of my favorite guitar players. However, my checklist has the following requirements: light weight, easy to move around, loud, lots of headroom, and good clean tone.


Pre-Amp

For the pre-amp section, I chose the Kingsley Maiden BF tube pre-amplifier. Based on the classic Fender Blackface design, this powerful little preamp is powered by a 9V AC adapter and fits nicely on a pedal board. The Maiden BF features controls for Volume, Master, Treble, Middle and Bass, as well as a 3-way bright switch (labeled Mode). In addition, pulling up the Midrange pot activates a mid boost. Kingsley also makes a version of the Maiden based on the clean channel of a Dumble ODS type amplifier. This version they call the Maiden D. Update 2024: Currently using the Sarno SMS Pre.

Power Amp

For the power amp section I chose the Seymour Duncan PowerStage 170. There’s a nice demo of the Maiden BF going into a Seymour Duncan PowerStage 700 (The bigger/louder version of the PowerStage 170). The PowerStage 170 is a 170 watt Class D amplifier with a 3-band global EQ and a large volume knob, plus it’s small enough to fit on a pedal board. It has one input and one output to connect to a 4-16 ohm speaker cabinet. Update 2024: Currently using a MosValve TubeWorks RT2100 Power Amp.

Speaker

For the speaker I chose a Beyma Liberty-8, 12” speaker, because it’s advertised as sounding similar to a JBL E-120 speaker, considered to be one of the best speakers for guitar amplification. The Beyma Liberty-8 can handle up to 300 watts at 8 ohms, which should be a good fit for the PowerStage 170 amplifier.

Speaker Cabinet

For the speaker cabinet, I chose CaseOutlet’s 1×12” solid pine, raw wood, speaker cabinet. It has the option to be open or closed back. The price is nice, and it can be finished or left as raw wood.
