DIY Troubleshooting Guide

This guide covers the most common "it doesn't work" scenarios.

Step 1: The "Cold Start" Check

• • Is it actually on? Check that your guitar and amp volumes are up and your cables are fully plugged in.

  • Isolate the pedal: Remove it from your pedalboard and test it alone with just your guitar, amp, and one working power supply.

Step 2: Power & Polarity

• • Polarity Check: Ensure you are using a center-negative 9V adapter (the standard for most pedals).

  • Battery Check: If using a battery, test with a brand-new one. Old batteries are a top cause of "gated" or weak sound.

Step 3: Internal Visual Inspection

• • Solder Joints: Look for "cold" joints (dull/grey instead of shiny) or "solder bridges" (extra solder touching two separate pins).

  • Component Orientation: Ensure polarized parts like Electrolytic Capacitors, Diodes, and ICs are facing the right way. Check the notch on the IC against the layout.

Step 4: Signal Probing

• • If you have a multimeter, check if the DC voltage is reaching the power pins of your transistors or Op-Amps (usually ~9V).

DIY 奇難雜症檢查手冊 (Troubleshooting Guide)

呢篇指南會同大家掃描一吓最常見嘅「部機郁都唔郁」死機大鑊嘢。

步驟 1：「起步」基本檢查 (Cold Start Check)

• 其實開咗機未？ 睇吓你支結他同埋部 Amp 個 Volume 扭大咗未，同埋啲 Cable 有無真係插實、隊到最底。

• 獨立測試個 Effect： 將佢拆離你成塊 Pedalboard，淨係用支結他、一部 Amp，同埋一個肯定行得通嘅火牛單獨試佢，排除其他雜音源。

步驟 2：電源同正負極 (Power & Polarity)

• 檢查正負極 (Polarity Check)： 確保你用緊 Center-Negative（內負外正 嘅 9V 火牛，呢個係絕大部分 Effect 嘅標準規格）。

• 檢查舊電芯 (Battery Check)： 如果你係用電芯，即刻換粒全新嘅試試。粒電就快乾塘（打柴）係最常引致啲聲好似被 Gate 住或者極度虛弱嘅元凶。

步驟 3：睇入面 PCB (Internal Visual Inspection)

• 錫位（焊點）： 望吓有無「假焊 / 凍焊」（啲錫望落暗啞、灰啡色，而唔係令身有光澤嘅），或者有無「搭橋」（多出嚟嘅錫無意中連住咗兩隻獨立嘅 Pin 腳）。

• 零件方向： 確保有分正負極/方向嘅零件，例如電解電容（Electrolytic Capacitors）、二極管（Diodes）同埋 IC（集成電路晶片）無掉轉裝，睇吓 IC 上面個凹位（Notch）有無對正。

步驟 4：訊號探測 (Signal Probing)

• 如果你手頭上有部萬用表（他表），去量吓啲直流電（DC Voltage）有無去到你粒三極管（Transistor）或者 Op-Amp（運放晶片）嘅供電 Pin 腳（正常嚟講應該係 9V 左右）。
