Overview

The Monoprice 611705 5-Watt Guitar Combo Tube Amplifier punches well above its price class by pairing genuine tube circuitry with a respected Celestion Super 8 speaker. The preamp stage runs on an ECC83/12AX7 tube, feeding into a 6V6GT power tube — a classic pairing known for producing smooth, harmonically rich overdrive with plenty of dynamic response. At just 5 watts, this amp reaches natural tube saturation at volume levels that won't overwhelm a bedroom or home studio, making it an ideal platform for recording where cranked-amp tone is the goal without excessive decibel levels.

The dual-input design adds a useful layer of versatility. The High input delivers the full signal to the preamp, making it easy to push the tubes into breakup with hotter pickups or an aggressive playing style, while the Low input attenuates the signal by roughly half for players who want more clean headroom. The frequency response of 80 Hz to 10 kHz keeps the amp focused on the guitar's core tonal range. While the 8-inch speaker and low wattage mean this amp has clear physical limitations for stage use, its combination of authentic tube character, a quality speaker, and an accessible price makes it a compelling option for practice, recording, and small acoustic settings.

Key Features

As the title indicates, this guitar amplifier features a 5-watt tube power amplifier and a Celestion brand speaker.

It uses a ECC83/12AX7 preamplification tube and a 6V6GT power tube for the amplifier section, plus a Celestion Super 8 GBA-15 speaker.

The amplifier handles frequencies between 80Hz and 10kHz, with hum and noise -75dB below the rated power and 0.5% total harmonic distortion.

It includes a low input and a high input, with the former attenuating the signal by approximately 50% and the latter being easier to overdrive.

While tone is always debatable, the increased dynamic range and even-order harmonic distortion of tubes produces the better sound.

Pros & Cons

👍 Pros

Real tube preamp and power section deliver warm, dynamic tone with natural harmonic richness.
Celestion speaker provides quality sound reproduction that exceeds expectations at this price point.
Low 5-watt output allows you to achieve tube overdrive at bedroom-friendly volumes.
Dual input jacks offer flexibility between clean headroom and easier breakup.
Compact and lightweight form factor makes it easy to transport and store.

👎 Cons

5-watt output is too quiet for most live performance situations without PA support.
Limited onboard controls with no built-in effects, reverb, or EQ beyond basic tone shaping.
Frequency response of 80 Hz to 10 kHz rolls off highs compared to full-range amplifiers.
Single-channel design offers no footswitchable clean-to-overdrive option.
Eight-inch speaker produces less low-end fullness than larger 10- or 12-inch alternatives.

Frequently Asked Questions

What tubes does the Monoprice 611705 use?

It uses an ECC83/12AX7 tube in the preamp stage and a 6V6GT tube for the power section.

What is the difference between the Low and High inputs on this amp?

The Low input attenuates the incoming signal by approximately 50%, keeping the tone cleaner at higher volumes. The High input passes the full signal, making it easier to drive the tubes into natural overdrive.

Is this amp loud enough for gigging?

At 5 watts, it can handle small, intimate venues and café-style gigs, but it will likely be underpowered for larger stages without microphone support through a PA system.

What speaker is installed in this amplifier?

It comes equipped with a Celestion Super 8 GBA-15 eight-inch speaker.

Can this amp be used for recording?

Yes, its low wattage makes it well suited for recording, as you can push the tubes into overdrive at manageable volume levels to capture rich, saturated tones.
