Seeing Through the Bullsh*t: The Truth About This Famous Pedal

Summary

In this video, Marco dives deep into the Boss GE7 and GE B7 EQ pedals, exploring the myths and truths surrounding their use and modification. After testing the noise and sound quality of stock and modified versions, he examines the impact of changing op-amps and capacitors. While the modded version offers a slightly softer high-end sound, Marco emphasizes that while mods can enhance performance, they aren't necessary for everyone. Ultimately, he provides insightful advice for those considering pedal modifications, stressing that it's a personal choice and not a must for improving guitar playing.

Takeaways

• 😀 The Boss GE7 and GE B7 EQ pedals are essential tools for guitarists, with a focus on modding and the myths surrounding them.
• 🎸 The main difference between the GE7 (older, Japanese) and GE B7 (newer) lies in their EQ curves and the op-amps used for filtering.
• 🔊 Testing noise levels is important when comparing the two pedals; both are nearly identical in noise levels when flat, but differences arise when settings are cranked.
• 🎶 The GE7 is modified with a NE5532 op-amp, while the stock GE B7 uses the JRC 4558 op-amp. These differences impact noise levels and tonal characteristics.
• 💡 The GE7’s noise can be reduced by swapping out the TL022 op-amps for quieter options like the NE5532, while the newer GE B7 doesn’t exhibit significant noise problems.
• 🔧 Modding the pedals involves changing op-amps and capacitors, but it’s not always necessary for improving noise or tone, especially with the newer models.
• ⚡ Capacitor changes, particularly replacing tantalum capacitors, can make a noticeable difference, but it’s not always crucial unless you're using low-quality capacitors.
• 🔍 The process of modding involves socketing new ICs, swapping capacitors, and testing the result. The video showcases some of the upgrades applied.
• 🎛️ High-end op-amps like the OPA 2134 were tested in mods, which resulted in a perceived ‘softness’ in the high-end frequencies of the pedal sound.
• 💭 Modding may improve the sound for enthusiasts, but it’s not essential to become a better guitar player, and the impact on the noise floor might be minimal.
• 🛠️ While the modding process can be rewarding for those who enjoy tinkering, for most guitarists, stock versions of the Boss pedals are more than adequate for use.

Q & A

What is the main focus of the video?

The main focus of the video is discussing the Boss GE7 and GE B7 EQ pedals, including their differences, modifications, and the myths surrounding them.

What is Marco's perspective on modding these pedals?

Marco acknowledges that modding the pedals can improve them but emphasizes that it’s not necessary for everyone. He suggests that while mods can enhance the pedals, especially the older versions, they may not be essential for most users.

What is the difference between the Boss GE7 and the GE B7 pedals?

The Boss GE7 is an older version, built in Japan, while the GE B7 is a newer version. The GE7 has a different EQ curve, and the B7 uses SMD technology, which affects modding capabilities.

How does noise behave in the GE7 and GE B7 pedals?

When the pedals are set to flat settings, there is no noticeable difference in noise. However, when cranked, both pedals introduce some noise, but the noise levels are relatively similar. The modded GE7 seems to have less high-end noise compared to the stock GE B7.

What modifications does Marco perform on the GE B7?

Marco modded the GE B7 by replacing op amps with high-end audio op amps (OPA 2134), and he also swapped out certain capacitors for improved audio quality.

What is the impact of modding the op amps in the GE7 and GE B7 pedals?

Modding the op amps can improve the sound quality by reducing noise, especially in the older GE7 versions that use the TL022 op amps. In newer models like the GE B7, the stock op amps are already relatively low noise.

What is Marco’s opinion on capacitor modifications?

Marco believes that capacitor swaps can make a difference but only if done strategically. He suggests that swapping electrolytic capacitors for tantalum capacitors is a good upgrade. However, he is cautious about replacing film capacitors unless absolutely necessary, as larger capacitors can cause issues with size and practicality.

Do the capacitor mods significantly affect the sound?

Marco suggests that while capacitor mods can make a difference, especially with low-quality components, the change might not be drastic. He points out that small changes in capacitors may offer some improvement but not always a major impact on the overall sound.

Does the modded GE7 pedal offer a noticeable improvement in noise?

Yes, the modded GE7 pedal has noticeably lower noise, especially in the high-end frequencies, compared to the stock version. However, the noise improvement is more apparent in older GE7 pedals that use the TL022 op amps.

Should everyone mod their Boss EQ pedals?

No, Marco clarifies that while modding can provide improvements, it is not necessary for everyone. If you're happy with the sound and don't want to dive into technical modifications, the stock pedals are perfectly fine.
