Review EARTH SOUND RESEARCH Vintage 70s Stagemaster Solid Statehead Guitar

The EarthQuaker Devices EarthQuaker Sound Research PA-2000 70s Stagemaster Solid State Head is a versatile and powerful guitar amplifier head that delivers a rich, warm, and dynamic tone reminiscent of classic 1970s amplifiers. This amplifier head is not to be confused with the PA-2000 model produced by EarthQuaker Devices in their effects pedal line, but rather the Sound Research division's homage to the legendary 70s amplifiers.

The PA-2000 70s Stagemaster Solid State Head is a 2-channel, all-tube-preamp, solid-state power amplifier that produces 35 watts per channel into 8 or 16 ohms. The first channel is a bright and clear channel, perfect for clean and crunch tones, while the second channel is a thick and warm overdrive channel, capable of delivering everything from mild break-up to full-on distortion.

The amplifier head features a three-band EQ on each channel, allowing for fine-tuning of bass, mid, and treble frequencies. The input gain controls for each channel offer plenty of headroom and are designed to be responsive to the player's touch. The presence control on the second channel adds a mid-range boost, adding depth and character to the overdriven tones.

The PA-2000 70s Stagemaster Solid State Head also features a footswitchable reverb effect, which adds a beautiful and lush ambiance to the sound. The reverb can be adjusted using the internal damping control, allowing for a wide range of reverb tones, from short and snappy to long and lush.

The amplifier head's solid-state power section ensures reliable and consistent performance, while the all-tube preamps deliver the warm and dynamic tone of classic tube amplifiers. The PA-2000 70s Stagemaster Solid State Head is housed in a rugged, road-worthy steel chassis, with a vintage-style control panel, making it not only a high-performing amplifier, but also a visually stunning piece of equipment.

Whether you're a seasoned professional or a beginner looking to add a versatile and powerful amplifier to your rig, the EarthQuaker Sound Research PA-2000 70s Stagemaster Solid State Head is an excellent choice. With its rich and dynamic tone, versatile channels, and built-in reverb effect, this amplifier head is sure to inspire and impress.

The EarthQuaker Devices (previously known as Earth Sound Research) PA-2000 70s Stagemaster is a solid-state guitar amplifier head known for its vintage design and versatile tone. Here are some pros and cons that may help you make an informed decision about purchasing this amplifier head:

1. Versatile tone: The Stagemaster offers a wide range of tones, from clean and crisp to overdriven and distorted, making it suitable for various musical genres.

2. Vintage design: Its retro aesthetic, with knobs and controls reminiscent of 1970s amplifiers, adds to its appeal for players seeking an authentic vintage look and feel.

3. Affordable: Compared to high-end tube amplifiers, the PA-2000 is relatively more affordable, making it an attractive option for budget-conscious guitarists.

4. Durable: Solid-state technology provides a more reliable and durable amplifier head compared to tube amplifiers, which can be prone to issues like tube failure.

1. Limited headroom: The Stagemaster may struggle to deliver clean tones at higher volumes, making it less suitable for players who require a lot of volume or a pristine clean sound.

2. Limited power: With a power output of only 20 watts, this amplifier head may not be sufficient for larger venues or gigs where a more powerful amplifier is needed.

3. Lack of reverb: Unlike some amplifier heads in its price range, the PA-2000 does not come with an onboard reverb effect, which some players might find disappointing.

In conclusion, the Earth Sound Research PA-2000 70s Stagemaster solid-state guitar amplifier head offers a versatile range of tones, a vintage design, affordability, and durability. However, it may not provide the headroom, power, or built-in effects that some guitarists require.

If you're a player seeking a versatile, affordable, and durable amplifier head with a vintage aesthetic, the PA-2000 could be an excellent choice for you. However, if you require a more powerful amplifier or the added effects of reverb, you may want to consider other options. Ultimately, the decision comes down to your personal preferences and requirements.

Details:

All others interested in a cool PA/Guitar head send your reasonable offers. Vintage PA that has found new life with guitar players as an head. Vintage solid state Sound with a real spring reverb. All is working aside from channel 3 Sounding a bit quieter and troubled than the others, likely only component or two that needs replacement.

Some scratchy pots to be expected but all works and it puts out a fair amount of Sound from my 4x12. In pretty good shame for its age, see photos.
